A small jet carrying six people crashed into a densely populated neighborhood in Northeast Philadelphia on Friday night, igniting multiple fires and prompting a major emergency response.

The Federal Aviation Administration (FAA) confirmed the aircraft was a Learjet 55, which had departed from Northeast Philadelphia Airport and was en route to Springfield-Branson National Airport in Missouri.

Initially, the FAA reported only two people were aboard, but U.S. Transportation Secretary Sean Duffy later stated that six were believed to be on the flight.

There has been no official confirmation of survivors or casualties, though local media footage showed a massive fireball followed by burning buildings and vehicles. FOX29 broadcasted images of thick plumes of smoke rising from the crash site.

Pennsylvania Governor Josh Shapiro posted on X (formerly Twitter) that emergency services were actively responding and that the state was providing all available resources. “We’ll continue to provide updates as more information becomes available,” he wrote.

The Philadelphia Office of Emergency Management labeled the situation a “major incident” and urged residents to avoid the area near Roosevelt Mall, where multiple roads were closed. First responders, including police and fire crews, worked to contain the blaze and assess the damage.

This crash comes just two days after a catastrophic collision between a passenger jet and a military helicopter near Washington’s Reagan National Airport, which killed 67 people—the deadliest U.S. aviation disaster in nearly 25 years.

Authorities, including the FAA and the National Transportation Safety Board (NTSB), have launched an investigation into the cause of the crash.
