Millions of dollars worth of damage has been caused to eight private jets in Houston after strong winds brought down an airport hangar.

The Jet Linx hangar collapsed in 60mph gusts at around just before midnight on Tuesday at Hobby Airport and debris was scattered across the runway.

Nobody was in the hangar at the time and there were no reported injuries, airport spokesman Bill Begley said.

"Straight line winds blew the hangar over onto several jets inside the hangar," Lieutenant Larry Crowson of the Houston Police Department said.

"To our knowledge, nobody was in the hangar during the failure of the structure."

Airport officials said up to eight aircraft were damaged in the private terminal but no commercial flights are affected.
