PHILADELPHIA, Feb 1, (AP): A medical transport jet transporting a child who had just completed treatment for a life-threatening condition, her mother and four others crashed into a Philadelphia neighborhood shortly after takeoff Friday evening, exploding in a fireball that engulfed several homes. Jet Rescue Air Ambulance, which operated the Learjet 55, said in a statement: "We cannot confirm any survivors.”

There was no immediate word whether anyone on the ground was killed, but at least six people were treated for injuries at a hospital. Everyone aboard the flight was from Mexico. The child was being transported home, according to Jet Rescue spokesperson Shai Gold. The flight’s final destination was Tijuana after a stop in Missouri.

The patient and her mother were on board along with four crew members. Gold said this was a seasoned crew and everyone involved in these flights goes through rigorous training. "When an incident like this happens, it’s shocking and surprising,” Gold told The Associated Press. "All of the aircraft are maintained, not a penny is spared because we know our mission is so critical.”

Pennsylvania Gov. Josh Shapiro said at a news conference late Friday that officials expected fatalities in the "awful aviation disaster.” "We know that there will be loss,” he said. A spokesperson for Temple University Hospital-Jeanes, Jennifer Reardon, said they had treated six people with injuries from the crash. Three of those people had since been released and the others were in fair condition.

She wasn’t able to provide information about their injuries or where the people were when they sustained them. The plane was registered in Mexico. Jet Rescue is based in Mexico and has operations both there and in the U.S. The crash came just two days after the deadliest U.S. air disaster in a generation. On Wednesday night, an American Airlines jet carrying 60 passengers and four crew members collided in midair in Washington, D.C., with an Army helicopter carrying three soldiers.

There were no survivors. The Philadelphia crash was the second fatal incident in 15 months for Jet Rescue. In 2023 five crewmembers were killed when their plane overran a runway in the central Mexican state of Morelos and crashed into a hillside. In Philadelphia, a doorbell camera captured video of the plane plunging in a streak of white and exploding as it hit the ground near a shopping mall and major roadway.
