My first flight in a T-38, about 100 ft, I retract the gear and see a flock of birds pass very quickly by us accompanied by numerous "thuds" The fragile J-85's didn't burp..I tell my instructor that I think we took some birds, and he starts railing about how that was the sound of the gear retracting!! He then starts lecturing me about how I had approx 2 minutes of T-38 time and he had over 700 hours, and I should not question him, etc etc...great start with a guy who holds my future in his hands. As we block in, the crew chief starts pointing to us and a few others come by to look, blood and guts everywhere, and a required engine change on one engine!!! My instructor never apologized. Flying C-141's at 300 ft, I've must have had hundreds of bird strikes, we just wrote it up upon landing. Nowadays, the military is so cautious concerning birdstrikes that we have to land immediatley to inspect the aircraft!!! great policy if your finished with your training and want to land early!!!!
