Analysis

The on-demand air taxi flight struck a moose during the takeoff roll at a private rural airstrip. The two pilot crew and one passenger were uninjured. The leading edge of the aircraft's left wing was substantially damaged; but the pilot-in-command elected to fly the aircraft to its original destination 30 NM distance. The flight was completed without further incident.
