Of course, the only way to prove this would be to either randomly pull models off the flight line for a "tear-down inspection" of the piston and the "igniter" OR have each competitor "supervised" during prep and right up until the model & piston is placed on the flight line. If the model is taken down, for any reason, the process repeats.
