MARATHON (CBSMiami) — A small plane crashed in the Florida Keys Thursday afternoon.

The Piper PA-32 plane was taking off from Marathon Airport’s runway around 3:30 p.m. That’s when, according to a passenger, the plane was lifting off and was caught by a gust of wind that caused the plane to be blown over into the tree line on the west side of the runway.

The plane crashed into the woods and caught fire, sources said.

Four people were injured in the wreck.

Two people were taken to Ryder Trauma Center at Jackson Memorial Hospital.

The injuries are not burn related but primarily broken bones, according to sources.

None of the injuries are considered life-threatening.

Authorities have identified those injured as Pilot Roch Aoust, 65, of Panama City; Tony Lewis, 60, of Lakeland; Derrick Kelley, 53; and Danny Gilileo, 49, of Auburndale, Florida.

The airport was closed down for a short time after the crash but has since reopened.

The aircraft is registered to All Pro Auto Parts Inc. of Auburndale, Florida. The plane can carry up to seven passengers.

The FAA is investigating the incident. The NTSB will determine the cause of the crash.
