Two Centuries Under the Lens:

The Greenbelt Corridor From Bladensburg to Roman

A 19-square-mile patch of suburban Maryland captured by an astronaut from the International Space Station holds the densest concentration of U.S. military, aerospace, and civil-science heritage anywhere outside the National Mall — and is now the locus of three simultaneous federal disputes that will shape the next decade of civil space science.

 

By Pseudo Publius — Special to Aviation Week — April 24, 2026

BLUF — 

A NASA Earth Observatory Image of the Day released April 22, 2026, showing the I-495 corridor through Greenbelt, Maryland, captures one of the most institutionally dense rectangles in the United States. Within and immediately adjacent to the frame lie the August 24, 1814 battlefield at Bladensburg — the  ground over which a foreign army has fought and marched on the U.S. capital; College Park Airport, the world’s oldest continuously operating airport, established by the U.S. Army Signal Corps for the Wright Brothers in 1909; the 1798–1812 Rossborough Inn, predating the University of Maryland itself and used as a Confederate cavalry headquarters in 1864; the former Naval Ordnance Laboratory at White Oak, where Nitinol, Bismanol, the Polaris fuze, and Space Shuttle hypersonic models were developed and which now houses FDA headquarters; the Henry A. Wallace Beltsville Agricultural Research Center; the New Deal-era Old Greenbelt National Historic Landmark; and NASA’s Goddard Space Flight Center, the agency’s first space-flight complex, where the $4.3-billion Nancy Grace Roman Space Telescope completed final performance testing on April 21, 2026, ahead of a September 2026 Falcon Heavy launch. Three federal disputes are active in the same geography: a 25% Goddard footprint reduction under contested FY2026 budget authority; a federal lawsuit by Maryland and Prince George’s County over the diverted FBI headquarters site at Greenbelt Metro; and ongoing congressional review of preemptive science-mission terminations. Every layer in the photograph — from War of 1812 powder smoke to the dark-energy-survey telescope shipping to Cape Canaveral in June — is alive in some form on the public record this week.

The Frame From Orbit

Astronaut photograph ISS069-E-39302 was acquired with a Nikon D5 at 1,150 mm focal length on July 30, 2023, by a member of the Expedition 69 crew. The ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit at Johnson Space Center released the processed image on April 22, 2026, with annotations identifying Greenbelt Park, the Old Greenbelt historic district, the I-495 Capital Beltway, the University of Maryland in College Park, and Goddard Space Flight Center. The photograph — a near-vertical view from low Earth orbit at roughly 408 km altitude — resolves individual cul-de-sacs, the Beltsville Agricultural Research Center fields, and the parking lots of NASA’s east campus.

What the released frame does not annotate is two centuries of accumulated military, aviation, and scientific heritage running through the same ground — the historical layers that explain why so many federal institutions are clustered here, and why the contemporary disputes over their futures are politically combustible.

1814: The British March Through

The Anacostia River drainage that defines the southern edge of the orbital frame is the same ground over which Major General Robert Ross’s 4,500-man British expeditionary force advanced on August 24, 1814. Landed at Benedict, Maryland on August 19 and marched fifty miles overland from the Patuxent, Ross’s force — veterans of the Napoleonic Wars, freed for North American service after Napoleon’s April 1814 abdication — arrived at Bladensburg, four miles south of present-day College Park, around midday.

The American defense was a hastily assembled mix of approximately 6,500 regulars, militia, and a 400-sailor naval contingent under Commodore Joshua Barney, deployed under Brigadier General William H. Winder, a political appointee who had been captured the previous year at Stoney Creek. Most of the militia broke within the first hour. Barney’s sailors and Marines, manning naval guns at the third American line, fought to the point of being surrounded; Barney was wounded and captured. The rout — mocked in contemporary accounts as the “Bladensburg Races” and described by later historians as “the greatest disgrace ever dealt to American arms” — opened the road to Washington. Ross’s troops entered the capital that evening and burned the Presidential Mansion, the Capitol, the Treasury, the War Office, and the Navy Yard. It remains the only successful capture of the U.S. capital by a foreign power.

The lineages of two American units that fought at Bladensburg — the 5th Maryland Regiment and the Columbian Division — are perpetuated today by the 175th Infantry (Maryland Army National Guard) and the HHD/372nd Military Police Battalion (D.C. Army National Guard). The British battle honor “Bladensburg” was awarded to the 4th, 21st, 44th, and 85th Regiments of Foot. National Park Service interpretive infrastructure at Bladensburg Waterfront Park is being expanded under an American Battlefield Protection Program grant administered through the Anacostia Trails Heritage Area.

The Rossborough Inn: A Pre-Federal Survivor on Route 1

One mile east of the Bladensburg battlefield, on the same Baltimore–Washington Turnpike that became Route 1, the tavern-keeper John Ross began construction of a brick stagecoach inn in 1798; the building was complete and operating by 1803–04, with later finishing work documented through 1812. Ross had previously operated the Indian Queen Tavern in Bladensburg before purchasing roughly 200 acres in what is now College Park and naming the property “Ross Borough.”

By 1858, the property had passed to Charles Benedict Calvert, who incorporated the inn and 420 acres of his Riversdale plantation into the founding endowment of the Maryland Agricultural College. The Rossborough Inn is, accordingly, older than the institution that absorbed it. In July 1864, during Jubal Early’s raid on Washington, Confederate cavalry under Brigadier General Bradley Tyler Johnson briefly occupied the campus and used the building as headquarters. The Inn later housed the federally chartered Maryland Agricultural Experiment Station beginning in 1888, and was extensively renovated by the Works Progress Administration in 1937–38 at a cost of approximately $30,000 ($19,042 of which was the original WPA grant). Today the structure houses the University of Maryland’s Office of Undergraduate Admissions and remains the oldest building on campus and in College Park, fronting U.S. 1 a few hundred feet from the building — Turner Hall — that was the original 1924 home of the campus dairy.

McKeldin Library and the Campus’s Natural-Hazard Record

At the western anchor of McKeldin Mall — the largest academic mall in the United States — stands the Theodore R. McKeldin Library, opened in 1958 and named for the former Maryland governor. The eight-floor structure houses the university’s general collection, the East Asia Collection, and the regional Federal Depository Library serving Maryland, Delaware, and the District of Columbia (a status the UMD library system has held since 1925; the regional designation was awarded in 1965). The library predates the construction of the Capital Beltway and the establishment of Goddard Space Flight Center. Outside its main entrance — since 1965, when it was relocated there from Maryland Stadium and filled with approximately 700 pounds of cement and steel rods to discourage further theft — sits the original 1933 bronze Testudo statue by Aristide Cianfarani, the Class of 1933’s gift to the university. Generations of students have rubbed Testudo’s nose for luck on entering the library; the bronze on the snout is visibly polished as a result.

For the aerospace and defense reader, McKeldin is a less obvious data point than NASA Goddard or NOL White Oak, but its building has accumulated a quietly remarkable record of natural-hazard exposure that bears on infrastructure-resilience analysis for the broader corridor.

The Blizzard of 1966. The North American Blizzard of 1966 is the corridor’s benchmark winter event of the past sixty years. The nor’easter, which struck January 29–31, 1966 (with antecedent storms beginning January 22–23), produced 13.8 inches at Washington National Airport and 12.1 inches at Baltimore. Federal employees in Washington were excused from work on Monday, January 31; international airports closed from Boston to Washington; an estimated 201 deaths were attributed to the storm complex across the affected region from Tennessee to Maine. For UMD students of the 1965–66 academic year, the blizzard was the most significant disruption of the era, but it caused no structural impact on the campus.

The September 24, 2001 F3 tornado. A long-track multivortex F3 tornado — one of two spawned that afternoon by a supercell complex moving northeast under 45–55-knot wind shear — touched down in Crystal City, Virginia at 5:03 PM EDT and reached the College Park campus at approximately 5:24 PM. With peak winds estimated at over 200 mph — high enough that the storm would be classified EF5 under the post-2007 Enhanced Fujita scale — it produced an approximately 30 km damage track from west of the campus to Laurel and into Howard County, where it dissipated near Snowden River Parkway. On-campus damage included roof and window damage to Denton and Easton Halls, the destruction of the ten triple-wide and portable trailers then housing the Maryland Fire and Rescue Institute (MFRI) immediately north of the President’s Mansion, the displacement of 200–300 vehicles in Parking Lot 2, and roof damage to the newly opened Clarice Smith Performing Arts Center. Two University of Maryland undergraduates — sisters Colleen and Erin Marlatt, daughters of an MFRI staff member — were killed when their vehicle was lifted from a roadway and thrown approximately 300 yards into a wooded area; a third tornado-related death occurred elsewhere in the storm path. On-campus damage was estimated at $15 million, statewide damage at approximately $73 million, and damage across the entire path at over $100 million. Debris from the MFRI trailers was recovered up to 60 miles away in northern Harford County, Maryland and southern York County, Pennsylvania. McKeldin Library, then twelve hundred feet east of the tornado’s closest approach, sustained no significant damage.

The Mineral, Virginia earthquake of August 23, 2011. The library was less fortunate when, at 1:51 PM EDT on August 23, 2011, a magnitude 5.8 earthquake struck with epicenter near Mineral, Louisa County, Virginia — the strongest seismic event in the Eastern Seismic Zone since 1944, and the most widely felt earthquake in U.S. history by population. At McKeldin, contemporaneous staff estimates put the number of books shaken from shelves between 13,500 (UMD Libraries internal count) and approximately 27,000 (figure later cited by American Libraries Magazine and based on full clean-up tallies). Compact shelving on three floors was compromised; one unit tilted off its track. A free-standing bookshelf on the fourth floor collapsed. Surface cracks appeared in two stairwells and at the tops of pillars on the first floor. Library staff loaded the displaced volumes onto approximately 150 book carts within twenty-four hours; only about 700 items required preservation treatment. Materials also fell from shelves at Hornbake, Art, Architecture, and Engineering and Physical Sciences libraries. McKeldin Library was closed pending structural engineering review.

The same earthquake caused the closure of the Washington Monument until 2014 for repairs to its pyramidion, cracked the central tower of the National Cathedral, and delayed the dedication of the Martin Luther King Jr. Memorial. For the corridor under examination here, it is a useful reminder that even systems engineered for civilian use in the East — where seismic codes are less stringent than on the West Coast — are not immune to the kind of structural disruption that, in a different building, could have been catastrophic for irreplaceable holdings. The library’s 4-million-volume collection emerged with a documented loss of fewer than a thousand volumes requiring treatment.

1909: The Wright Brothers and the World’s Oldest Airport

Three miles north of the Rossborough Inn, on a 160-acre tract leased on August 25, 1909 by the U.S. Army Signal Corps and selected by Lieutenant Frank Lahm from a balloon ascent, College Park Airport (FAA LID: CGS) opened operations that fall when a Wright Type A biplane, uncrated October 7, was assembled and flown by Wilbur Wright. Wright’s assignment was to train the first two military pilots in the United States — Lieutenants Frederic Humphreys and Frank Lahm. The Army had moved its flight-training operation to College Park because Fort Myer’s parade ground, where Orville Wright had crashed in September 1908 (killing Lieutenant Thomas Selfridge, the first powered-flight fatality), was inadequate for sustained operations.

Civilian flight operations began at College Park in December 1911, establishing what the Federal Aviation Administration, Maryland Department of Transportation, and National Park Service all recognize as the world’s oldest continuously operating airport. Subsequent “firsts” at the field constitute a partial syllabus of early American aviation:

• 1909: Mrs. Ralph H. Van Deman, first woman in America to fly as an airplane passenger; Lt. George C. Sweet, USN, first naval officer to fly
• 1911: First U.S. Army flying school; instructors included future Army Air Forces commander then-Lt. Henry H. “Hap” Arnold and Lt. Thomas DeWitt Milling
• 1912: First testing of an aerial bomb sight and an aerial machine gun; Bernetta Adams Miller, first woman to demonstrate flight in a military aircraft (October 7)
• 1918: Inauguration of U.S. Post Office airmail service to Philadelphia and New York (Belmont Park) on August 12, with War Department trial flights beginning May 15
• 1920–24: Emile and Henry Berliner test the first helicopter with practical maneuvering capability
• Pre-WWII: First U.S. radio navigational aids for all-weather flight, and the first reported nighttime landing using acetylene ground lamps

The airport was placed on the National Register of Historic Places in 1977. The Maryland-National Capital Park and Planning Commission acquired the field in 1973 and operates it today; the adjacent 27,000-square-foot College Park Aviation Museum, opened September 12, 1998, holds Berliner Helicopter No. 5, a Wright Model B reproduction, and an original Curtiss-built Postal mail plane. Since 9/11, operations have been governed by Special Flight Rules Area restrictions imposed by TSA, FAA, and the Secret Service; pilots clear a one-time background check before being authorized to operate from the field.

1944–1997: Naval Ordnance Laboratory at White Oak

Twelve miles northwest of College Park, just across the Montgomery County line, the U.S. Navy began acquiring a 712-acre wooded site at 10903 New Hampshire Avenue in 1944 for the Naval Ordnance Laboratory. The lab was the lineal descendant of the Navy Mine Unit established at the Washington Navy Yard in 1918, which was merged with the Indian Head Experimental Ammunition Station in 1929 to form NOL. The Navy Yard had been overwhelmed by the magnitude of work required after the German aircraft-laid magnetic mine emerged as a strategic threat in early World War II.

NOL White Oak grew to over 300 buildings on a campus deliberately sited — in what was then farmland — well outside Washington under the wartime federal policy of dispersing mission-critical research from concentrated targets. (One Navy official, asked in 1945 whether the war would end before the laboratory was finished, replied: “That laboratory is not being built for this war.”) Functional groups were segregated by hazard category: administration and laboratories near the New Hampshire Avenue entrance, magnetics testing in the wooded 200 area, explosives storage and small-scale explosives testing, ballistics, and a hypersonic wind tunnel complex. The Phoenix/Casino building in the 100 area was used for nuclear-weapons radiation simulation of components and systems.

The technical output is hard to summarize briefly, but a partial list conveys the scope:

• Bismanol — an iron-manganese-bismuth permanent-magnet alloy (the “-nol” suffix is from NOL)
• Nitinol — nickel-titanium shape-memory alloy, named for nickel + titanium + NOL; now ubiquitous in medical stents, aerospace actuators, and seismic damping
• Polaris missile fuze work — carried out by Lee Reed and others, building on World War II proximity-fuze research
• Hypervelocity wind tunnel testing of Space Shuttle models for NASA
• Large Scale Gap Test (LSGT) — standard methodology for assessing shock sensitivity of solid rocket propellants
• Acoustics Division headed by John Vincent Atanasoff, inventor of the first electronic digital computer
• Laboratory work associated with two-time Nobel Prize physicist John Bardeen
• Cofounder of Teledyne, Inc., Henry Earl Singleton, was an NOL alumnus

Under BRAC 1991 the staff was reduced to 650; BRAC 1993 disestablished the laboratory entirely. Weapons-systems research transferred to NSWC Dahlgren, explosives research to NSWC Indian Head, and basic research to NSWC Carderock (the former David Taylor Model Basin). The site closed in 1997 and approximately 600 acres were conveyed to the General Services Administration as the Federal Research Center at White Oak; 137 acres had been transferred to the Army in 1969 for the Harry Diamond Laboratories (now the U.S. Army Research Laboratory’s Adelphi facility). Under the FDA Revitalization Act of 1990, with construction funding approved in 1999 and groundbreaking in 2000, 130 acres became the consolidated U.S. Food and Drug Administration headquarters. The former NOL Administration Building — with the words “Naval Ordnance Laboratory” still carved in stone above the main entrance — was renovated to LEED-NC 2.0 Gold standard in 2008 and now anchors the FDA campus, which the 2018 GSA master plan envisions accommodating up to 18,000 employees in approximately one million square feet of additional space. Trichloroethylene contamination from former NOL operations remains under active CERCLA management; an air-stripping unit treats groundwater migrating onto the adjacent Army property.

The Federal Cluster Visible in the Frame

The Beltsville Agricultural Research Center

The large green area in the upper portion of the orbital photograph — a mix of forested land and agricultural fields — is the Henry A. Wallace Beltsville Agricultural Research Center, established in 1910 when the Department of Agriculture purchased the 475-acre Walnut Grange plantation. The Wallace name was added in June 2000. BARC today operates more than 7,000 acres and houses the USDA Agricultural Research Service’s Animal Genomics and Improvement Laboratory; the laboratory’s long-running joint program with Israel’s Agricultural Research Organization on dairy-cattle genetic-evaluation methodology was recognized in September 2020 by the U.S.–Israel Binational Agricultural Research and Development (BARD) Fund as one of the top three most economically impactful projects in BARD’s 40-year history.

NASA’s Goddard Space Flight Center

NASA’s Goddard Space Flight Center, established as the agency’s first space-flight complex on May 1, 1959, occupies 1,270 acres immediately east of the Beltway. The land was carved directly from BARC; until May 1959, the facility was known officially as the Beltsville Space Center, and was renamed for rocketry pioneer Robert H. Goddard at the recommendation of NASA Administrator T. Keith Glennan. Goddard’s first 157 employees transferred from the Naval Research Laboratory’s Project Vanguard.

Goddard has been the integration and operations home of TIROS-1, the Cosmic Background Explorer, the Hubble Space Telescope, the Tracking and Data Relay Satellite System, the Lunar Reconnaissance Orbiter, the Solar Dynamics Observatory, the James Webb Space Telescope, and the upcoming Nancy Grace Roman Space Telescope. The center has held more than 800 patents, sent more than 300 satellites to orbit, and contributed to a Nobel Prize in physics. As recently as 2019, the workforce stood at approximately 13,000 civil servants and contractors. That figure now stands at approximately 6,600 — a one-third reduction in a single year — through buyouts, the federal Deferred Resignation Program, and early retirements.

The contraction follows the White House’s fiscal-year 2026 budget request, transmitted in May 2025, proposing an overall NASA top-line of approximately $18.8 billion (a 24% cut from FY2025) with science programs cut by roughly 47%. Under the proposal, Goddard would lose more than 42% of its remaining staff. Congress has not enacted the request: the House would hold NASA flat, and the Senate has proposed $24.4 billion. NASA continues to operate under continuing resolutions.

Despite the absence of an enacted budget, Goddard leadership began implementing a facilities consolidation plan in September 2025, with building closures continuing through the 43-day federal government shutdown that ended November 12, 2025. The International Federation of Professional and Technical Engineers, parent of the Goddard Engineers, Scientists and Technicians Association, reported in a November member brief that 13 buildings on the west side of the campus were marked for closure by March 2026, with nearly 100 laboratories to be emptied or displaced. The largest research library in NASA, holding more than 100,000 volumes including pre-digital mission documentation, was closed January 3, 2026. On October 30, 2025, the Senate Committee on Commerce, Science, and Transportation, under ranking member Maria Cantwell (D-Wash.), released findings concluding that NASA leadership had been prematurely implementing the FY2026 request before congressional enactment — a posture that, if sustained, raises Impoundment Control Act questions. NASA officials disputed the characterization. A 2025 executive order reclassified portions of NASA as covered by national-security exemptions, suspending collective-bargaining negotiations.

The Roman Counter-Narrative

Against this backdrop, Goddard delivered, on April 21, 2026, the most important programmatic milestone in U.S. astrophysics this decade: completion of comprehensive performance testing of the Nancy Grace Roman Space Telescope. Roman, a 2.4-m wide-field infrared observatory derived from a National Reconnaissance Office heritage primary mirror, will fly to Sun–Earth L2 aboard a SpaceX Falcon Heavy. NASA Administrator Jared Isaacman, announcing the milestone at Goddard, confirmed an early-September 2026 target launch — eight months ahead of the formal May 2027 commitment date — with the spacecraft to ship to Kennedy Space Center in mid-June. The mission has held to its $4.3 billion lifecycle cost. Roman’s 288-megapixel Wide Field Instrument will image fields roughly 200 times larger than Hubble’s WFC3, supporting three high-priority surveys (High-Latitude Wide-Area, High-Latitude Time-Domain, and Galactic Bulge Time-Domain) and demonstrating a Jet Propulsion Laboratory coronagraph instrument that is a critical pathfinder for the proposed Habitable Worlds Observatory. The FY2027 budget proposal, which Isaacman began defending before the House Science Committee on April 22, 2026, again seeks a 47% cut to NASA science and the cancellation of more than 50 missions including the Chandra X-ray Observatory.

Old Greenbelt: A New Deal Artifact Still in Use

The crescent-shaped historic district visible north of Greenbelt Park is the federally planned community of Old Greenbelt, one of three “greenbelt towns” built by the Resettlement Administration under economist Rexford G. Tugwell between 1935 and 1938. (The other two are Greenhills, Ohio, and Greendale, Wisconsin; a fourth, planned for New Jersey, was not built.) Construction was performed largely by Works Progress Administration labor; the Farm Security Administration added approximately 1,000 defense-housing units in 1941–42. The complete Greenbelt plans were reviewed at the White House by President and Mrs. Roosevelt on April 30, 1936; the first tenants moved in on September 30, 1937. The 756.8-acre district was placed on the National Register of Historic Places on November 25, 1980, and elevated to National Historic Landmark status on February 18, 1997. The federal government sold the housing stock to a veterans’ cooperative in December 1952; today, Greenbelt Homes, Inc., holds title to roughly 1,600 units, and the central Roosevelt Center grocery and the local newspaper (originally The Greenbelt Cooperator) remain cooperatively operated.

The FBI Headquarters Litigation

The Greenbelt Metro station, just north of the orbital frame, is the contested locus of the most consequential federal real-estate dispute in the corridor. After a 15-year process, GSA Administrator Robin Carnahan announced in November 2023 that Greenbelt had been selected from three congressionally designated sites — Greenbelt and Landover in Maryland and Springfield in Virginia — for the new FBI headquarters, citing taxpayer cost, transit access, and project-delivery certainty. Then-FBI Director Christopher Wray publicly disputed the process; the GSA Inspector General opened a probe; GSA legal counsel found Wray’s concerns to be without merit. Congress had appropriated more than $1.1 billion across multiple statutes between 2016 and 2024; Maryland and Prince George’s County had committed an additional $300 million in transportation and parking infrastructure based on the federal selection.

In July 2025, the FBI and GSA jointly announced that the bureau would instead occupy the Ronald Reagan Building and International Trade Center on Pennsylvania Avenue — a site not among the three Congress had designated. FBI Director Kash Patel cited cost-effectiveness; GSA documents indicated $1.4 billion in renovation costs at the Reagan Building, including $95 million in fire-protection upgrades and $38 million in structural repairs.

On November 6, 2025, Maryland Attorney General Anthony Brown and Prince George’s County filed suit in U.S. District Court against the Trump administration, seeking to block the Reagan Building selection and prevent diversion of approximately $555 million in already-appropriated funds. The complaint alleges that the executive branch ignored an explicit congressional directive limiting selection to the three pre-designated sites and that redirection of the funds requires affirmative action by the House Transportation and Infrastructure Committee and the appropriations panels — action that has not occurred. The state estimates the Greenbelt project would, if restored, produce 7,500 jobs and roughly $4 billion in regional economic activity. Governor Wes Moore, Senators Chris Van Hollen and Angela Alsobrooks, and Representative Glenn Ivey have publicly endorsed the litigation. The Department of Justice declined to comment on pending litigation; the General Services Administration, which under prior leadership had defended the Greenbelt selection, also declined to comment.

Why This Corridor Matters to the Aerospace Reader

The Greenbelt corridor has no production lines, no tier-one assembly facilities, no flight-test infrastructure of contemporary military significance. Its strategic value is institutional and historical: a 19-square-mile rectangle that has, in turn, hosted the only successful invasion of the U.S. capital, the world’s first military aviation training, the laboratory where Nitinol and the Polaris fuze were developed, the nation’s first land-grant agricultural research enterprise, the largest U.S. agricultural-research campus, NASA’s civil-science integration capability for Earth-observing, heliophysics, and astrophysics flagship missions, the principal land-grant university partner for that capability, and the federal law-enforcement real-estate dispute with the largest current dollar value.

The astronaut photograph released April 22, 2026, was almost certainly intended as a routine Earth Observatory feature on the New Deal-era greenbelt-town concept and the persistence of urban tree canopy. Its timing places it on the public record at a moment when much of the institutional infrastructure visible — and audible, in adjacent White Oak — is being restructured at a pace and under legal conditions that the affected agencies, unions, lawmakers, and Article III courts dispute.

For an aerospace audience, the relevant data point is straightforward. The Roman Space Telescope is on track to launch from Cape Canaveral in September 2026 on a Falcon Heavy — a mission planned, designed, and integrated in a campus where, six months earlier, employees were moving equipment out of laboratories during a federal government shutdown, on land originally carved from a USDA agricultural research station, three miles from where the Wright Brothers trained the first Army pilots, four miles from where the British army marched on Washington, and fifteen miles from where the Polaris missile fuze was perfected. Both kinds of facts are true at the same time. Both will continue to be true at least through the FY2027 budget cycle.
