LOS ANGELES (AP) 鈥� The B-52 involved in a deadly crash during a test flight at an made a sharp right and then nearly completed a 180-degree turn before plunging to the ground at nearly a mile a minute, limited tracking data shows Tuesday.
All eight people aboard were killed in Monday’s fiery crash of the B-52 Stratofortress, which was taking part in a routine mission as part of an overall program to keep the long-running aircraft flying for decades to come. It was not yet clear what caused the plane to crash shortly after takeoff, and officials at Edwards Air Force Base said it could take up to six months to complete the investigation.
The airfield remained closed Tuesday. Crews were making the crash site safe for search and recovery teams to enter, after fires flared up overnight, said Mike Paoli, a spokesperson for the 412 Test Wing at Edwards.
The flight tracking that was available Tuesday shows the bomber turning to the northeast right after taking off and nearly completing a sharp turn before crashing on another runway, according to AirNav Systems. The data that comes from a system called multilateration doesn鈥檛 show precise altitude and speed information, but it does show the plane fell to earth at a rate of descent of 5,056 feet (1,541 meters) per minute 鈥� nearly 10 times as fast as a plane normally descends when preparing to land.
The aircraft was supporting a 鈥渞adar modernization program,鈥� Col. James Hayes, the deputy commander for the 412 Test Wing, said Monday. In 2025, Boeing sent a B-52 to Edwards with a modernized radar system that is key to keeping the bomber in the air through at least 2050, nearly a century after it first entered service.
A test team planned to conduct ground and flight test activities on the aircraft throughout 2026 to feed a production decision, the Air Force said in a 2025 news release. The modern Active Electronically Scanned Array (AESA) radar system replaced the aircraft鈥檚 antiquated radar for efficacy. It was unclear if that was the same aircraft involved in Monday鈥檚 crash.
AESA replaced 1960s radar technology and offers improved navigation and targeting capabilities, according to a 2023 news release from Raytheon, which designed the new system for the Air Force’s entire B-52 fleet.
B-52 began flying in the 1950s
The B-52, a long-range bomber that entered service in 1955, is designed to carry both conventional and nuclear weapons. It has been to Iran.
Along with a new radar, the fleet of 76 B-52s are scheduled to receive additional upgrades, including new engines, crew compartments, conventional and nuclear communication systems, avionics and weapons. The military said the goal is to make the B-52 a complement to the Air Force鈥檚 newest strategic bomber, the .
Aerial footage showed virtually nothing left of the aircraft that went down at the base in the Mojave Desert about 100 miles (161 km) northeast of Los Angeles. Officials determined no one could have survived after reviewing footage of the crash, Hayse said at a news conference.
Those on the B-52 included government contractors and uniformed military. Aircraft manufacturer Boeing confirmed that two of its employees were on board.
Edwards is home to a large portion of the U.S. Air Force鈥檚 aircraft test and development efforts. The 412th Test Wing, which runs the base, also conducts developmental testing of all Air Force aircraft, weapons systems, software and components before purchase by the service as well as throughout their lifespan.
The base is where reached a speed of Mach 1.05 and broke the sound barrier in 1947.
Investigators will focus on how quickly the crash came
The way the B-52 crashed so quickly after takeoff without getting very high or going far makes aviation safety expert Jeff Guzzetti suspect some kind of flight control malfunction.
It鈥檚 possible the controls were rigged wrong after maintenance, he said, or a catastrophic engine problem or a failure of a piece of equipment that was being tested.
鈥淚 think it was definitely a controllability issue. Now, whether that was tied to an engine failure, a flight control failure, or some new testing device failure, I鈥檓 not sure,鈥� said Guzzetti, who used to investigate crashes for both the Federal Aviation Administration and the National Transportation Safety Board.
In recent years, fatal Air Force training accidents in the U.S. have included an in 2024 when the ejection seat activated while the aircraft was still on the ground in Texas and an in a 2022 accident involving a Humvee during a training exercise in Idaho. Two Air Force pilots were killed when a near an Alabama airport in 2021.
