A US Air Force Boeing B-52 Stratofortress crashed on Monday shortly after taking off from the Edwards Air Force Base in California, the base said.
"Emergency crews immediately responded to the scene, and the situation is ongoing," the base wrote in a post on X/Twitter.
The crash occured at 11:20 a.m. local time, according to the base.
The eight-engined strategic bomber has been in service for over 70 years, with current engineering analyses indicating the aircraft's lifespan will extend past 2040, according to the US Air Force Strike Command's website.

With a wingspan of 185 feet (56.4 meters), the B-52 can be equipped with the widest array of weapons in the US military's inventory, the website said.
According to the website, the aircraft is capable of flying at high subsonic speeds at altitudes up to 50,000 feet (15,166.6 meters) and can carry both nuclear and conventional ordinance.
