When the engine refused to produce power over Aspen, I was still indicating about 100 mph and was almost 400 feet agl. If you have ever flown out of Aspen, you know that when departing downhill, there are no options down-valley for a forced landing. As I slowed the Cub to best gliding speed, I keyed the mic and told my buddy to break right as I was reversing course to land on Runway 15. By the time the course reversal was complete, I was back to 60 mph and on a good glidepath to make the runway with energy to spare. By the time I was 50 or so feet above the ground, the prop had come to a complete stop. I touched down, turned off the runway, coasted up onto the ramp, spun the Cub around and hopped out to the roaring applause (well, OK then, the baffled looks) of all those who had observed me from behind the fence at the FBO. Was this dead-stick landing a big deal? I didn't think so, not because of any outstanding ability on my part, but because of my extensive training as a glider pilot.
