Airport '77 (1977)

An airplane filled with V.I.P.s invited Mr. Philip Steven's grand opening of his art collection in Florida is hijacked when a trio knock out the passengers with gas and try to steal the priceless cargo of art treasures. But everything goes wrong for the hijackers when the low flying 747 clips an oil rig and crashes in the Bermuda Triangle. While the passengers remain alive in the shallow water, a daring rescue operation is planned to bring the plane up without breaking it in two.
