B-52 on test flight plunged at a rate of nearly a mile a minute before crashing, killing 8

LOS ANGELES (AP) — The B-52 progressive successful a deadly clang during a trial formation astatine an Air Force basal successful California made a crisp close and past astir completed a 180-degree crook earlier plunging to the crushed astatine a complaint of astir a mile a minute, constricted tracking information shows Tuesday.

All 8 radical aboard were killed successful Monday's fiery clang of the Boeing B-52 Stratofortress, which was taking portion successful a regular ngo arsenic portion of an wide programme to support the long-running craft flying for decades to come. It was not yet wide what caused the level to clang instantly aft takeoff, and officials astatine Edwards Air Force Base said it could instrumentality up to six months to implicit the investigation.

The airfield remained closed Tuesday. Crews were making the clang tract harmless for hunt and betterment teams to enter, aft fires flared up overnight, said Mike Paoli, a spokesperson for the 412 Test Wing astatine Edwards.

The formation tracking that was disposable Tuesday shows the bomber turning to the northeast close aft taking disconnected and astir completing a 180 grade crook earlier crashing connected different runway, according to AirNav Systems. The information that comes from a strategy called “multilateration” doesn’t amusement precise altitude and velocity information, but it does amusement the level fell to world astatine a complaint of descent of 5,056 feet (1,541 meters) per infinitesimal — astir 10 times arsenic accelerated arsenic a level usually descends erstwhile preparing to land.

The craft was supporting a “radar modernization program,” Col. James Hayes, the lawman commandant for the 412 Test Wing, said Monday. In 2025, Boeing sent a B-52 to Edwards with a modernized radar strategy that is cardinal to keeping the bomber successful the aerial done astatine slightest 2050, astir a period aft it archetypal entered service.

A trial squad planned to behaviour crushed and formation trial activities connected the craft passim 2026 to provender a accumulation decision, the Air Force said successful a 2025 quality release. The modern Active Electronically Scanned Array (AESA) radar strategy replaced the aircraft’s antiquated radar. It was unclear if that was the aforesaid craft progressive successful Monday’s crash.

AESA replaced 1960s radar exertion and offers improved navigation and targeting capabilities, according to a 2023 quality merchandise from Raytheon, which designed the caller strategy for the Air Force's full B-52 fleet.

B-52 began flying successful the 1950s

The B-52, a long-range bomber that entered work successful 1955, is designed to transportation some accepted and atomic weapons. It has been utilized successful conflicts involving the U.S. subject from Vietnam to Iran.

Along with a caller radar, the fleet of 76 B-52s are scheduled to person further upgrades, including caller engines, unit compartments, accepted and atomic connection systems, avionics and weapons. The subject said the extremity is to marque the B-52 a complement to the Air Force’s newest strategical bomber, the B-21 Raider.

Aerial footage showed virtually thing near of the craft that went down astatine the basal successful the Mojave Desert astir 100 miles (161 km) northeast of Los Angeles. Officials determined nary 1 could person survived aft reviewing footage of the crash, Hayes said astatine a quality conference.

Those connected the B-52 included authorities contractors, Boeing employees and uniformed military.

Edwards is location to the 412th Test Wing, which conducts regular developmental investigating of each Air Force aircraft, weapons systems, bundle and components earlier acquisition by the work arsenic good arsenic passim their lifespan. Test missions instrumentality spot astatine Edwards daily, Hayes said.

The basal is wherever Air Force trial aviator Chuck Yeager reached a velocity of Mach 1.05 and broke the dependable obstruction successful 1947.

Investigators volition absorption connected however rapidly the clang came

Aviation information adept J. Joseph said that often erstwhile a clang happens astatine precise debased altitude close aft takeoff, a occupation with the formation controls oregon engines is involved. But it is inactive excessively aboriginal to cognize what caused this tragedy, said Joseph, a retired Marine Corps colonel and hose pilot.

Even successful a B-52 with 8 engines, a malfunction tin marque the level hard to power if the aviator loses the outboard engines, and the forces pushing the level get retired of equilibrium successful a information Joseph called asymmetric thrust.

And helium said that erstwhile thing goes incorrect this adjacent to the crushed the aviator has precise small accidental to bash anything.

“There’s a batch of options with altitude, a batch of options, with airspeed. And that is simply a precise captious signifier of formation close aft takeoff,” Joseph said.
