Eight people were killed in a B-52 bomber crash at Edwards Air Force Base in southern California on Monday, according to base officials. The aircraft went down immediately after take-off during what officials described as a routine test mission, sending a large column of black smoke into the sky near the Mojave Desert installation.

The crash happened at 11:20 local time, or 19:20 GMT. Col James Hayes said the victims were a “mixed crew of military, government civilians and government contractors.” Boeing later confirmed that two of its employees were among those on board.

At an afternoon briefing, Hayes said the bomber had been supporting the base’s radar modernisation programme when it crashed just after take-off and burst into flames.
