[PC][Early 80s]Flight sim that erased itself if you crashed

Platform(s): PC

Genre: Flight Sim (Stunt flying)

Estimated year of release: 1980

Notable gameplay mechanics: When playing on the hardest difficulty, it would erase the game from the floppy if you crashed your plane.

Other details: I believe it was made by Ken Roberts or someone else at Sierra (maybe Al Lowe?)

I only read about it in an article, never actually played it.
