Paul Lewis, 40, was rescued Friday from the roof of the hangar in Whitchurch, Shropshire, by a firefighter and treated for head and neck injuries, The Daily Telegraph reported.
Colin Fitzmorris, owner of the Parachute Center, saw the jump and said Lewis' main parachute didn't open, and his reserve chute didn't function properly. Lewis is a freelance cameraman and was filming tandem jumps for the skydiving firm.
Firefighters took Lewis to the University Hospital of North Staffordshire, in Stoke-on-Trent. A spokesman said the hangar roof was flexible, and Lewis didn't suffer any broken bones but had a minor neck injury.
