22 March 1956: While carrying the U.S. Navy’s Douglas D-558-II Skyrocket, problems developed aboard both the research rocketplane and the “mothership.” The modified four-engine heavy bomber, a U.S. Air Force Boeing B-29-95-BW Superfortress (which had been transferred to the U.S. Navy and redesignated P2B-1S Superfortress), had a runaway propeller on the Number 4 engine, outboard on the right wing. The propeller broke apart from excessive rotational speed, slicing through the Number 3 engine, the fuselage, and striking the Number 2 engine.
NACA research test pilot John Barron (“Jack”) MacKay, in the cockpit of the Skyrocket, had called “No drop!” because of problems with the rocketplane, but he was jettisoned so that the mothership could maintain flight and make an emergency landing.
McKay dumped the Skyrocket’s propellants and glided to the lake bed.
“Each rocket-plane pilot had worked out, in conjunction with the pilot of the mother ship, a procedure to follow if any emergency developed in either plane. Jack McKay, who had developed into a very able test pilot, and I had agreed with Butchart that if something went wrong after either of us had entered the cockpit of the Skyrocket and had closed the canopy, he would immediately jettison the rocket plane, leaving the rocket-plane pilot to look after his own hide. As a matter of fact, McKay and Butchart later ran into such an emergency. One day something went haywire in a propeller on the B-29 mother plane. As agreed, Butchart instantly cut loose the Skyrocket. A split second later the B-29 prop tore loose and cartwheeled through the space the Skyrocket had just vacated. McKay landed without difficulty; but had Butchart not cut the parasite plane loose, the prop would have ripped into its fuel tanks, causing an explosion that would have killed everyone, including McKay.”

The Superfortress pilots, Stanley Paul Butchart and Neil Alden Armstrong, landed the plane safely on the lake bed at Edwards Air Force Base.
Neil Armstrong would land on The Moon 13 years later.

The legendary Tuskegee airmen will mark their 80th anniversary on March 22. It was on that date in 1941 that President Franklin D. Roosevelt activated the all-black world war two fighter squadron. They were the first African American aviators in the U.S. armed forces.
Interesting. . .I have read much about Neil Armstrong, and knew that he was a Navy fighter pilot in Korea, but I have never read anything that said he was qualified in B-29’s, or any other four engine aircraft. Could someone enlarge upon this?
My great uncle, Gene May, made the very first flight in the Skyrocket, he was also the first to fly it supersonic, and was the first to publicly display supersonic flight with a low level pass at a public. That was also is last flight in the Skyrocket as Bill Bridgeman took over the program.
Thanks, Steve. Bridgeman talked quite a bit about Gene May in his book, The Lonely Sky. . . See TDiA for 14 April 1947 at https://www.thisdayinaviation.com/14-april-1947/
