A tragically similar stuck pogo scenario also resulted in perhaps the first U-2 fatality, at Groom Lake May 15, 1956. Article 345, 56-6678 crashed killing Wilburn S. "Billy" Rose.
From the NASA publication
Unlimited Horizons (2015):
One incident with deadly results was a consequence of the unusual landing gear arrangement. As originally designed, the pogo outriggers were to be dropped during or shortly after takeoff using a manual release system. “We soon learned that any delay by the pilot in dropping them would often cause them to hang up,” Ernie Joiner recalled. “When that happened, it was wise to stay clear of the airplane’s flight path.”
On May 15, CIA pilot Wilburn S. “Billy” Rose had just taken off for a training flight in Article 345 when he noticed that one of the outriggers had failed to separate. He tried to shake it loose while flying low over the lakebed but the airplane, heavy with fuel, stalled and crashed. Rose became the first CIA fatality of the program. To prevent a reoccurrence of the problem, the pilot actuation system was removed so that the pogos would fall away automatically as soon as the wings started to lift, while the airplane was still on the runway. A spring was installed on the upper end of the pogo to push it away from the wing as soon as the weight of the aircraft was lifted.
An excellent list of U-2 production and disposition (and sadly,
a lot of fatalities
) is in Appendix 2 of this book.
