A recent special operations exercise in California in early July revealed one of the dangers of military free-fall operations.

During the exercise, a British commando’s primary parachute failed to deploy properly. The operator deployed his reserve parachute, but it didn’t have enough time to inflate properly, leaving him to fall 15,000 feet.

The malfunction meant he fell straight through the roof of a civilian house, landing in the kitchen. Surprisingly, the British commando wasn’t seriously hurt, only suffering minor injuries, according to local law enforcement.

For personal security purposes, the British Ministry of Defense didn’t release the name or the unit of the lucky parachutist.

However, only a select few British special operations units receive military free-fall training. So it’s safe to assume that the commando is a member of the Special Air Service (SAS), Special Boat Service (SBS), the Special Reconnaissance Regiment (SRR), the Special Forces Support Group (SFSG), or the Pathfinders.
