In my opinion it is one thing to deceive flying organisations with false claims of solo flying.
However doing it at a service charity dinner is another. No doubt giving them all the false claims without mentioning Ewald Gritsch and his place onboard the Stearman.
I believe the military slang for such a person is a Walt. Abreviation of Walter Mitty.
