US Airways Express flight US4206 returned to land at Harrisburg International Airport, Pennsylvania, USA after sustaining a bird strike on departure. The aircraft, a DHC-8-102, encountered a flock of geese.
The captain was the pilot flying and the first officer was the pilot monitoring. According to the flight crew, about 15 seconds into the takeoff roll and prior to V1, the captain observed a large group of geese flying from right to left in front of the airplane.

The flight crew shut down the right engine as the airplane slowed and returned to the gate.
