I'm not a true rocket scientist but "I do play one on TV". Actually all those loud snoring type noises were from me testing the Shuttle's engines. All systems checked out okay. The primariy reason for the crash was the clean-up crew left too much fish slime on the pitch and yaw pedals and I was not used to that much lubrication - NTSB decision - pilot error.
