American Marconi Wireless News - Philadelphia plane crash marks a second US aviation disaster

Video footage appeared to show the twin-engine plane descending at a sharp angle towards 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 6:00 pm (2300 GMT). Data from tracking site FlightAware suggested the aircraft was used to transport medical patients.

Jet Rescue Air Ambulance told US media in a statement there were two passengers, including a pediatric patient, 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.

US President Donald Trump on Friday took to his Truth Social platform and said he was "sad" to see "more souls lost" in the Philadelphia tragedy. He praised first responders, adding: "God Bless you all."

Several witnesses told local TV crews that they saw body parts in or near the wreckage, as Philadelphia City Council member Mike Driscoll said he feared there were several casualties, potentially including residents or others on the ground.

"It doesn't look good. And it's a sad situation here," he told CNN.

Pennsylvania Governor Josh Shapiro gathered with local officials near the crash zone as he lamented the "awful aviation disaster."

"We know that there will be loss in this region," he said.

The FAA said it was launching an investigation along with the National Transportation Safety Board.

- Washington tragedy -

Both agencies are already probing the deadliest US air disaster in almost a quarter century, after a passenger jet operated by an American Airlines subsidiary collided with a Black Hawk helicopter on Wednesday.

The airliner with 64 people onboard was coming in for a night landing at Reagan National Airport in Washington -- just a few miles from the White House -- when it collided with the US Army helicopter on a training mission.

Divers were scouring Friday for the remaining bodies in the frigid Potomac River, after having pulled at least 41 victims from the water.

Investigators on Friday found the helicopter's black box after having already retrieved the cockpit voice and flight data recorder from the Bombardier jet operated by an American Airlines subsidiary.

Officials are confident data can be fully extracted from the recorders, said NTSB member Todd Inman, adding an investigation was still being carried out.

However, the lack of clarity over the accident's cause did not deter Trump's politicized commentary.

He appeared to place blame on the military helicopter in a post on the Truth Social platform, saying it was "flying too high, by a lot."

This followed a news conference Thursday where the Republican pinned the blame for the crash on his Democratic predecessors Joe Biden and Barack Obama, claiming without evidence they had hired the wrong people due to non-discrimination initiatives known as DEI.

Chesley Sullenberger, who famously landed a stricken passenger plane on New York's Hudson River in 2009, told network MSNBC he was "disgusted" but "not surprised" by Trump's rhetoric.

Aviation experts, meanwhile, homed in on whether the helicopter crew could see through military night-vision goggles and whether the Reagan National Airport control tower was understaffed.

Interviews of staff who were in the control tower at the time of the crash have already begun, the NTSB said.

The collision was the first major crash in the United States since 2009, and the deadliest since an American Airlines jet crash in Belle Harbor, New York in 2001 that killed all 260 aboard.

Among those on Wednesday's doomed airliner were several US skaters and coaches, and Russian couple Evgenia Shishkova and Vadim Naumov, who won the 1994 world pairs title.

Two Chinese citizens and a Filipino were also among the victims.
