Not the most beautiful flying machine ever built - the Huey helicopter. It was butt ugly, noisy, slow, and easy to hit. But UH-1H "Gator 536" never failed to bring my Army butt home from many a combat assault. There were also a multitude of GI "grunts" who were either surrounded, wounded, tired, or sick to whom the rescuing Huey was the most beautiful sight in the word.
