Quoted: An AWACS flew through a flock of Canadian geese on takeoff and crashed a few years ago at Elmendorf AFB Alaska. IIRC the investigators concluded that both engines on the left were destroyed by the geese causing the crash.

Geese Caused AWACS Disaster
Pacific Air Forces released accident investigation board findings that confirmed earlier speculation that a flock of geese caused the crash of an E-3B Sentry in Alaska on September 22, 1995.
The Airborne Warning and Control System (AWACS) aircraft's two left-wing engines ingested several Canada geese, according to the official report released January 11.
"The result was an immediate, unconfined, catastrophic failure of the number two engine as well as compressor stalls in the number one engine," the report stated. It added that the E-3 began a "slow left-hand climbing turn, struck a hilly wooded area less than one mile off the departure end of the [Elmendorf AFB] runway and broke apart."
The crash killed all twenty-four crew members and destroyed the aircraft. [See "AWACS Crash Claims Twenty-Four Lives," November 1995 "Aerospace World," p. 14.]
What About Human Error?
The report ruled out crew error, stating that "the aircrew did everything humanly possible to fly this aircraft out of an unflyable situation." However, it did note two other factors that "substantially contributed to the accident."
One was the failure of the airfield tower controller to notify the AWACS crew or airfieldmanagement about a flock of geese that had been flushed when a C-130, using the same runway, took off just two minutes before the E-3 began its takeoff roll.
The second factor was that the base "lacked an aggressive program to detect and deter" the presence of the large birds and "did not adequately prepare for the migration season."
According to the report, the 3d Wing mistakenly believed its program was sound, based on an Air Force Safety Agency team's July 1995 endorsement of the wing's written plan to handle potential aircraft birdstrike problems.
Since the accident, according to a PACAF release, base officials have stepped up bird-control efforts to include increasing flight-line patrols and installing sound cannons to disperse the birds.
