Investigators are trying to determine what caused a medical jet to crash into a Philadelphia neighborhood on Friday, killing six people on board and one person on the ground.
"We haven’t seen anything like this," said Anthony Phillips, a Philadelphia City Council member, reflecting on the impact of the crash.
A child patient, a passenger and four crewmembers were aboard the plane when it crashed Friday night. The girl had just received lifesaving medical treatment at Shriner's Children's Hospital and was returning home to Mexico.
