2 Delta planes collide on tarmac at Atlanta airport, FAA says
Officials are investigating after a Delta plane collided with an Endeavor Air flight on the tarmac at Hartsfield-Jackson Atlanta International Airport in Georgia. Endeavor Air is a Delta subsidiary.
Delta Air Lines Flight 295, an Airbus A350, was taxiing for departure to Tokyo, Japan, shortly after 10 a.m., the Federal Aviation Administration said, when its wingtip struck the tail of Endeavor Air Flight 5526. The Endeavor plane, a Bombardier CRJ900 craft, was bound for Lafayette, Louisiana. The planes were on alternate taxiways when the collision happened, Delta said.
