A FedEx Boeing 727 cargo jet has crashed in flames just short of the runway at Tallahassee Airport in Florida.
The three crew members escaped serious injury.
The three-engine jet, from Memphis, Tennessee, landed half a mile short of the runway.
"We can't speculate on the cause," said FedEx spokesman Jess Bunn.
A hospital official said the crew were in fair condition. They were being checked for broken bones; they did not suffer burns, she said.
