Eight people, including two Boeing employees, were killed after a US Air Force B-52 Stratofortress bomber crashed immediately after takeoff from Edwards Air Force Base in southern California.
The incident on Monday took place during a routine test mission, sending a colossal plume of black smoke into the air that was visible for miles.
Officials described the tragedy as a severe loss, noting that the casualties comprised a mixed crew of military personnel, government civilians and defence contractors.
They also confirmed that the crash was entirely contained within the base runway, causing an immediate, temporary grounding of operations and the diversion of all inbound flights.
While initial reviews of the airfield footage led authorities to deem the incident completely unrecoverable and unsurvivable, the aircraft was reportedly supporting the military installation’s ongoing radar modernisation programme when it came down and burst into flames.
The aerospace giant Boeing confirmed that two of its personnel were among the deceased and stated that the company remains in direct contact with the grieving families.
While an official inquiry has been launched, authorities stated that determining the exact cause of the mechanical or operational failure could take up to 30 days, with comprehensive forensic analysis potentially lasting more than six months.
The B-52 is a long-range strategic bomber capable of carrying an immense 70,000-pound payload, including conventional bombs and nuclear cruise missiles. The massive aircraft has been actively utilised in recent bombing raids during the joint US and Israeli military campaign in Iran.
Following the disaster, California Governor Gavin Newsom and several US lawmakers publicly expressed their condolences, offering prayers for the first responders and the families of the eight crew members who lost their lives.
