By the way, it was common practice in those days for the instructor pilot to bet a bottle of booze with the student as to whether he (the student) would be quick enough to retract the gear and flaps on his first full AB takeoff before he exceeded the placarded gear speed of 250 knots. That's how quick the beast accelerated under max thrust, once you left the ground. It was akin to your first cat shot at the ship; the plane was up here, but your mind and reflexes were still back there. Once you got used to it, it was old hat, exhilarating and fun. By the way, more often than not, the instructor won.
