A risky stunt in which a bi-plane travelling inches off the ground at 200mph narrowly avoiding hitting two people is being investigated by Texan air authorities.

The footage was shot at Lancaster Municipal Airport, Texas, and shows the bi-plane hurtling towards the screaming cameraman and a quad bike rider.

Lancaster City manager, Opal Mauldin Robertson, told WFAA TV the pilot involved in the stunt had been identified and was registered at the airport.

He said: "The city will be fully cooperating with the Federal Aviation Administration in reviewing the activities of that pilot."

Daredevil group, Those Crazy Texans, are reported to be behind the clip which was a rehearsal for an upcoming show.
