Unhappy

Didn't want to do this but.....
"On Jan 9, '98 a B727-200 departed Houston Texas. Climbing through 6000 ft the crew heard a loud bang followed by much vibration. Noise level was so high, comm almost impossible.....the #1 engine lost some fan blades and vibration caused cowling doors to become unlatched.....#2 engine lost fan blades, #3 engine had a damaged pylon.... radome departed the aircraft along with the antenna...pressure bulkhead penetrated...leading edge of both wings damaged...kruger flaps (plus adjacent wing area)and inboard slat on right wing punctured...f/o's pitot tube torn off...$5,000,000 damage.
Cause of damage was collision with a flock of snow geese at 280 kt at 6000 ft asl.
The aircraft was doing high-speed departure trials.... to test for gains in efficiency.
The impact force increases with the square of speed......aircraft components like engenes, windshields, and leading edge devices are not designed to withstand high-speed impacts."
So no more high-speed departures/arrivals for me thank you, and I won't let ATC fly my airplane for me either.
