A US Airways jet headed to Fort Lauderdale aborted its takeoff in Philadelphia after the nose gear failed Thursday evening, airport and airline officials said.
The plane was briefly airborne before the pilot turned back, said the carrier, which is now owned by American Airlines.
All 149 passengers and five crewmembers aboard Flight 1702 were evacuated safely from the Airbus A320 and no injuries were reported. One photo posted on Twitter showed passengers being evacuated on the plane's emergency slides.
"All customers and crew have safely evacuated," said US Airways spokesman Todd Lehmacher. "Emergency crews are on scene. Passengers are in the process of being transported to the terminal."
The nose gear collapsed on the runway at 6:38 p.m., Philadelphia International Airport said. The flight had been scheduled to leave at 6:05 p.m.
"We believe the tire blew, causing the nose gear to collapse, while it was moving down the runway," spokeswoman Victoria Lupica said.
A ground stop to control plane traffic was in effect, the Federal Aviation Administration said. Three of the four runways were later reopened.
