Big Brass ones!
I once watched the lowest flying C5A in the world. At Mcord AFB, Washington, about 1979-80. It was on a Saturday, and the wife and I were in the AFB to attend a collage course. Just before we were to leave, the crash trucks, fire trucks and everyone and his dog went in the direction of the Air Strip. We walked out and saw the C5A flying in circles, and making strange movements. The fire crew started to put down foam, all over the strip. 20-30 min later, in came the Big Bad Boy! Looking good, but, no nose gear down. He got lower, and slower, and then lower! He greased that baby in, nose high, on the threshold limits. Used brakes and sounded like tad reverse thrust. Nose high. It seemed like he would never come down. When the pilot at last lost enough speed, he dropped the nose on down like a feather. It slid in the foam a long ways, before coming to a stop. A few hours later, the repair crew put a big fat pillow under the nose, inflated it, manualy dropped and locked the nose gear and took it to the shop. A few days later, it was gone. What a trip.
