Passengers were forced to use escape shutes to evacuate a US Airways aircraft after its landing gear collapsed.
More than 150 passengers and crew used emergency slides from the Airbus A320 at Philadelphia airport and other flights were halted.
One person asked for medical assistance but no major injuries were reported, airport officials said.
An airport spokeswoman said the aircraft was about to take off for Fort Lauderdale when the malfunction occured.
The Airbus was carrying 149 passengers and five members of crew.
Three of the four runways were reopened later on Thursday evening.
The airport spokeswoman told the BBC that all passengers had been rescheduled on another flight to their destination in Florida.
A US Airways spokesman said: “Initial reports indicate Flight 1702 from Philadelphia to Fort Lauderdale blew a tyre on take-off and the pilot elected to abort take-off.”
Passenger Dennis Fee told local broadcaster WPVI it was “very windy and when the plane took off, the nose of the plane went back down, hitting the runway”.
“We were airborne, then struck back down by the nose,” he said.
