The Role of Philadelphia Plane Crash Marks A Second U.S. Aviation Disaster

PHILADELPHIA, Pennsylvania — A small jet with six people onboard crashed into a busy Philadelphia neighborhood Friday, officials said, marking another US aviation disaster after a passenger plane and a military helicopter collided midair in Washington earlier this week.

Video footage appeared to show the twin-engine plane descending at a sharp angle toward a residential area, sparking a huge fireball upon impact and showering wreckage over homes and vehicles.

The Federal Aviation Administration (FAA) said the aircraft was a Learjet 55 — an American-French business jet — that had taken off shortly before from Northeast Philadelphia Airport bound for Branson, Missouri.

The crash happened just after 600 pm (2300 GMT).

A young girl who had been in the United States for medical care, her mother, and members of the flight and medical crews accompanying her onboard were killed in the crash, the children's hospital that treated her told Agence France-Presse.

The patient had received care from Shriners Children's Philadelphia and was being transported back to her home country in Mexico on a contracted air ambulance when the crash happened, said Mel Bower, a spokesman for Shriners Children's.

The aircraft's operator Jet Rescue Air Ambulance confirmed in a statement to US media that there were two passengers and four crew, adding, At this time, we cannot confirm any survivors.

Dozens of emergency workers were on the scene outside Roosevelt Mall, a strip mall in Northeast Philadelphia with retailers and food outlets.
