Passengers were forced make an emergency evacuation off a US Airways flight tonight after the nose gear reportedly collapsed shortly after takeoff at Philadelphia International Airport.

A passenger on the plane reported that the plane had "just started to get airborne" when the Airbus blew a tire, forcing it to abort takeoff as it skidded off the runway.

Philadelphia International has been put on a ground stop, which halts or slows all incoming flights, until "further notice." The airport tweeted that the accident is under investigationand no passengers were injured in the crash.
