Audio from an air traffic control tower in Philadelphia reveals the horrific moments before a medical ambulance plane crashed in Philadelphia Friday night while transporting a pediatric patient.

People gathered in the Northeast Philadelphia neighborhood from dawn to mid-afternoon to see what remained of Friday's nightmare. They stood yards away from a debris field of broken plane pieces and singed cars to get a glimpse of the wreckage.

A medical transport jet with a child patient, her mother and four others aboard crashed into a Philadelphia neighborhood shortly after takeoff, exploding in a fireball that engulfed several homes.
