WALLER, Texas (AP) — A skydiving instructor was killed after his parachute failed to open during a tandem jump in the Houston area, but his student survived the ordeal, authorities said.

Both were airlifted to a Houston hospital after the jump Saturday in Waller, about 40 miles (65 kilometers) northwest of Houston. The instructor later died and the student had serious injuries that aren’t life-threatening, Skydive Houston said.

Waller County Sheriff Troy Guidry said their parachute failed to deploy.

Skydive Houston says jump operations are suspended pending an investigation.
