No B-29 story would be complete without mentioning Neil Armstrongs single engine landing. he was co-pilot on a trip to drop the D-558-2 research aircraft. Approaching 30,000' the #4 had a prop runaway which came off and sliced through #3, which lost throttle control and instrumentation so was shut down, #2 was also hit. #1 was shut down because of torque, even with just #2 running it required both pilots on the rudder, even at low power. The D-558 pilot asked not to be dropped because of fuel pressure control problems, but was dropped in any event, which was fortunate as the prop on its path to hitting #2 passed through the bomb bay where the 558 had been slung, also severing the command pilots pitch and roll controls. Neil was the only one with a full set of functioning aerodynamic controls.
