On Monday, Delaware State Police identified the individuals who died in the crash: The pilot was 52-year-old Terrence Daniels of Philadelphia, and the instructor was 79-year-old Albert Dohring of Middletown, Delaware.
She said around 9 a.m., the twin engine plane, registered to a Philadelphia resident, took off from a runway at the New Castle Airport.
The pilot almost immediately notified air traffic control that they needed to return to the airport. After that, the plane crashed just 2 miles away from the runway.
Several agencies responded to the scene, "including 12 fire departments along with DNREC and a division of forensic science," Jaffe explained.
Authorities are still investigating what caused the plane to go down.
On Aug. 8, three passengers also died in a similar small plane crash in Upper Moreland Township. A family of three — a husband, wife and their daughter — died in the crash, which went down in a resident's backyard.
