An interesting sidenote to the discussion of the two pogo-related crashes above:
Lockheed Martin has a video on their site (see here:
The U-2 Dragon Lady · Lockheed Martin) that they label as showing the U-2's first flight. You can clearly see the pogos falling away during the take-off roll before lift off. More than one book describes the pogos as being released by the pilot after lift off until after the May 1956 accident, so I suspect that while this video shows a U-2 as flown early in the type's career, it was recorded after May 1956. Anyone else with thoughts about this?
I have a distinct feeling that there are more errors on that page by the way
