One person is dead and six others are injured in the fiery crash of a hot-air balloon Sunday evening in suburban Philadelphia's Chester County.

Emergency Services says one person died at the scene.
Two others were flown to Temple University Hospital in Philadelphia, where they're being treated in the burn unit.

Three were taken to the Chester Crozier Medical Center, where one is listed in stable condition and two are in stable condition.
The seventh person was treated at another hospital and released.

Several companies in the area offer recreational balloon flights. Authorities aren't sure which owned the balloon that crashed or what caused the accident.
