Northrop/DARPA–Air Force Tacit Blue (BSAX) first flew in 1982, testing curved-surface stealth and low-probability-of-intercept radar. Kept secret until a 1996 unveiling; airframe now at the National Museum of the USAF.

Project OXCART produced the CIA Lockheed A-12, a Mach-3+ reconnaissance aircraft that flew Operation BLACK SHIELD from Okinawa in 1967–68 (twenty-nine operational missions, including Pueblo imagery). CSI Archangel, The Oxcart Story, and Reading Room mission packets document design, deployment, and phase-out. The Archive refuses collapsing A-12 into generic SR-71 Vietnam lore or inventing Soviet overflights.

On 18–19 September 1980 a dropped socket punctured a Titan II Stage 1 oxidizer tank at Complex 374-7 near Damascus, Arkansas. Public framing stressed no nuclear yield and intact warhead recovery; ARAC/NEST paperwork, congressional narrative, and the Eighth Air Force board show a silo-destroying blast that killed SSgt David Livingston and threw the W-53 clear.

National Museum USAF and USAF declass packets document Constant Peg’s 4477th TES Red Eagles flying MiG-17/21/23 from Tonopah Test Range (1977–1988) as adversary training under deep classification, publicly reframed in the mid-2000s as a training program rather than a UFO wing.

On the night of 11 November 1979 TAE flight JK-297 diverted to an emergency landing at Manises (Valencia) after red lights appeared to pace the Super Caravelle; a Mirage F-1 scrambled from Los Llanos, the file was later declassified (Aug 1994), and Socialist deputy Enrique Múgica carried the case into the Cortes in 1980.

NTSB AAR-00/03 finds TWA Flight 800’s probable cause was a center wing fuel tank explosion, most likely from FQIS-related short circuit among evaluated ignition sources. FBI criminal investigation closed without a charged bomb/missile attack; CIA analysis reframed key rising-streak eyewitness reports as post-explosion aircraft motion. Contested/L2 keeps the missile hypothesis labeled contested beside the NTSB spine.

On 24 January 1961 a B-52 breakup near Goldsboro released two Mk 39 thermonuclear bombs. Public framing stressed the weapons stayed safe; Parker F. Jones's 1969 Sandia memo, later FOIA'd into view, concluded that on one bomb a single ready/safe switch was the last barrier to full yield.

On 17 January 1966 a Chrome Dome B-52 collided with a tanker over Palomares, Spain, releasing four B28 thermonuclear weapons. Public framing stressed safe/no nuclear yield; DNA, FRUS, and a FOIA'd State history document plutonium scatter ashore, months of Mediterranean recovery, and Franco's permanent ban on nuclear overflights.

On 21 January 1968 a Hard Head / Thule Monitor B-52 crashed on North Star Bay ice, rupturing four thermonuclear weapons without nuclear yield. Public framing stressed no danger; NS Archive / SAC History #113 / AEC Bruner packets document Crested Ice cleanup, a gentleman's agreement to remove contaminated ice, a missing spark-plug secondary, and the end of continuous nuclear airborne alert.

In December 2011 ISAF acknowledged a possible U.S. unarmed reconnaissance UAV lost after operators lost control over western Afghanistan; President Obama publicly asked Iran to return the aircraft, and Secretary Panetta supported that request on the record. Iranian electronic-warfare and reverse-engineering narratives are labeled claims. The Archive keeps documented/L2: loss and ask documented; mechanism edges contested.

NASA SP-4404 and CIA Oxcart histories document Lockheed CL-400 Suntan as a late-1950s USAF liquid-hydrogen reconnaissance concept cancelled on range and cryogenic basing grounds; dollar and performance edges stay carefully sourced under a contested verdict.

National Museum USAF and USAF packets document Boeing’s Bird of Prey as a 1992–1999 Phantom Works single-seat stealth demonstrator (fall 1996 first flight, ~38 flights) revealed and donated in 2002 after its LO and manufacturing techniques had already diffused into programs such as X-45A.

Lockheed Skunk Works Have Blue demonstrators proved faceted radar stealth, leading to the F-117 Nighthawk—publicly acknowledged 1988, displayed 1990. Documentary black-budget aviation without Aurora folklore.

After Lion Air (29 Oct 2018) and Ethiopian Airlines (10 Mar 2019) crashes killed 346, the House T&I Committee's Sept 2020 final report detailed MCAS design relying on a single AOA sensor, inadequate pilot disclosure, and FAA ODA failures.

CIA and NRO FOIA packets document Lockheed’s Mach-3 D-21 as Tagboard M-21 carriage ending in the fatal 30 July 1966 collision, then Senior Bowl B-52/D-21B China missions (1969–1971) cancelled 23 July 1971 after failed Lop Nor returns—ambitious failure, not a secret photo haul.

FRUS and CIA overhead packets document Air Force WS-119L/Genetrix camera-balloon reconnaissance from Western Europe in early 1956: limited usable film, Soviet camera displays, and an early-February presidential suspension under protest pressure while meteorological cover language stayed in the diplomatic note.

Museum, AFMC, DTIC, and NASA packets document USAF/Boeing X-20 Dyna-Soar as a 1957–1963 manned boost-glide program cancelled by SecDef McNamara on 10 December 1963 for cost, duplication, and weak military mission definition, with attention pivoting toward MOL—hypersonic residue without orbital flight.

SAC's Chrome Dome kept nuclear-armed B-52s on continuous airborne alert from 1961 until the day after Thule. NS Archive Greenland briefing books, SAC History #129, and FRUS Doc 21 show Hard Head over Greenland, neither-confirm-nor-deny host politics, and the 22 January 1968 end of nuclear airborne alert.

Strategic Air Command’s Looking Glass EC-135 airborne command post flew continuous alert from 3 February 1961 to 24 July 1990, carrying battle staff and Airborne Launch Control connectivity for ICBMs. FAS, USSTRATCOM, SAC Museum, NPS, and Minuteman NHS guides document the mission and the 1 October 1998 E-6B handoff. Documented/L1.

Museum, OSI, and GAO packets document Northrop/Boeing Senior Ice defeating Lockheed/Rockwell Senior Peg on 20 October 1981 in the classified Advanced Technology Bomber contest that became the B-2 Spirit—SAP industrial secrecy first, cost and concurrency oversight after unveil.

On 24 November 1971 the NORJAK hijacker ("Dan Cooper" / D.B. Cooper) extorted ransom and parachutes from Northwest Orient Flight 305 and exited via aft stairs; he was never found. FBI Famous Cases, Vault files, and the July 2016 Seattle resource redirect document the crime and state that tips never met beyond-a-reasonable-doubt identification. The Archive keeps identity contested/L2.

Soviet fighters destroyed KAL 007 after it strayed into Soviet airspace near Sakhalin (31 Aug/1 Sep 1983), killing 269. FRUS Controlled Fury, NSDD 102, Reagan Library files, and CIA FOIA show a managed U.S. crisis campaign; ICAO fact-finding later supported navigational deviation and condemned force against a civil aircraft.

Pan Am 103’s destruction over Lockerbie (270 dead) is documented. Megrahi’s Camp Zeist conviction (2001), 2002 appeal uphold, SCCRC referrals, 2021 High Court posthumous appeal refusal, and DOJ’s 2020 Masud Statement of Facts form the official spine. Contested exhibits—timer fragment, Malta identification, disclosure—remain live arguments. The Archive refuses closed-book certainty and framed-as-fact baptisms under contested/L2.

On 3 July 1988 USS *Vincennes* shot down Iran Air Flight 655, killing 290 people. The DoD Fogarty Formal Investigation, ICAO process, and ICJ *Aerial Incident of 3 July 1988* case (discontinued after 1996 settlement) form the primary spine. The Archive holds the shootdown as documented fact and keeps deliberate-massacre versus tragic-error intent language on L2 edges tied to those doors—not to slogans.
