Meritless accusations...? Really? Well this from the NTSB:-
Board member Robert L. Sumwalt criticized Leeward and his team for failure to adequately analyze, document, and test the modifications they made to squeeze more speed from the Galloping Ghost.
“The way I look at it quite honestly, is, if you’re flying, if you’re modifying an airplane without fully understanding how those modifications can affect aerodynamics, then you’re basically just playing Russian roulette with an aircraft,” Sumwalt said. “As the chairman said, unlike Russian roulette, in this case when you go out and you do those things, you not only endanger your own life, but you potentially endanger the lives of others, and that is what happened in this particular case.”
