5 injured during turbulence after plane takes off from Philadelphia International Airport (KPHL), Pennsylvania

PHILADELPHIA - May 4, 2014 (WPVI) -- Heavy turbulence injured five people and forced a plane to return back to Philadelphia International Airport shortly after takeoff. 

The US Airways flight from Philadelphia to Orlando took off just after 4:00 p.m. Sunday.

Mark Pensiero, who was one of about 300 onboard the plane, describes the scary moments.

"There was a very brief period in time where the plane felt like it wasn't in control and it wasn't. It was being moved by some pretty intense forces," he said.

Turbulence jolted some passengers.

Before the captain ordered the plane back to Philadelphia International, he asked for anyone with medical experience onboard to help.

Sources tell Action News that four people were taken to local hospitals and a fifth person refused medical treatment.

A 10-year-old child complained of head pain and was taken to Children's Hospital of Philadelphia.

A female passenger complained of head and back injuries and was taken to the Hospital of the University of Pennsylvania.

A 43-year-old male passenger complained of knee pain and was taken to Methodist Hospital.

A flight attendant complained of neck and back injuries. She was taken to Fitzgerald Mercy Hospital.

Pensiero says the spot where the flight attendant hit her head, made an indent on the plane's interior.

"When she hit her head on the side of the airplane, the part she hit cracked, she hit it hard," said Pensiero.

Action News is told that US Airways is inspecting the plane involved. Officials from US Airways have not returned our phone calls for comment.
