I get to work on our airforce base on occasion. Its a repair facility for the f 18 and some others.
Theres nothing like watching them test a new jet engine. The plane will creep along the runway for a few thousand feet...It looks liek a normal take off until the plane is about 100ft in the air, then its gone.
If you are standing right there you can count 1..1000....2...1000....three...1000 before you cant see it anymore. You almost want to look at a building, or the ground, because you feel like your eyes are not calibrated properly.
Its liek this video, but it happens in about 1/4 the time. When my income tax statement comes, I pretend my tax money went for this program and it makes it ok again.
