Fred Haise conducted tail flutter tests in a Piper PA-30 Twin Commanche. During the flight the horizontal tail surfaces fluttered so dramatically that Haise said after the flight: “I’m fearless, but that scares me.” On April 13, 1970, Apollo 13 suffered an oxygen tank explosion that forced the planned Moon landing to be abandoned.
