Got my license in 1962 in a tri-champ with 90hp and orange windows. My instructor sat behind me and beat me on the head, claimed i was trying to kill him!! He went on to head the Purdue Aviation Dept. and worked for the King's videos. Advanced training was in PT-17's, i remember watching a student bounce one the full length of a 5000' runway alternating between full power and glide and then going around and repeating the whole thing.
