Flying (improvised) IFR in Vietnam
Flying IFR, we had few instrument procedures, so we had to improvise most of the approaches. This led to some quite interesting approaches as you can imagine. For instance, going into Saigon when the weather was bad, if you called Approach for an instrument approach, you would be given probably 45 minutes to an hour and a half for an approach time. If that happened, we would set the radar altimeter to 200 or 100 feet.
