Vandenberg’s Space Launch Delta 30 unit confirmed that it triggered the alpha missile’s flight abort system and caused the explosion.

“A team of investigators will come together to determine the cause of the failure,” Space Launch Delta 30 said.

The Federal Aviation Office also determined. The agency told CNBC in a statement that no injuries or damage to public property were reported, but reports of possible debris falling to the ground are known.

Firefly’s Alpha missile is on the ground “until the FAA approves the final investigation report or determines that the issues related to the breakdown are not affecting public safety,” the agency added.

Firefly attempted to reach orbit when the company first launched, which would have been a rare feat for private rocket builders. Initial orbital launch attempts by other private rocket builders – SpaceX, Rocket Lab, Virgin Orbit, and Astra – suffered a multitude of failures, with the three former companies reaching orbit on later attempts.

A statement from Firefly stressed that its alpha test flight had achieved “a number” of mission objectives including: booster ignition, take-off and supersonic speed, and had collected “a significant amount of flight data”.
