A sense of uneasiness and disarray hung over a Northeast Philadelphia neighborhood Sunday, two days after an airplane plummeted into a busy street, killing at least seven people, injuring 22 others, and spewing wreckage for blocks.

The six people on board the Mexico-bound medical jet include a girl who had received life-saving treatment at a Philly children's hospital, her mother, a pilot, copilot, doctor and paramedic.
