I agree on having spare tires in the hangar....but sometimes on a contract flight you show up to a jet that has a bald spot and it's the mad rush to get the plane airworthy ASAP....I can't control what the other idiot does...but I am often called in to clean it up...It's a living.
I don't need to try you out Con...either what you say here makes sense or it doesn't..Resumes on the net are unverifiable...so save the 'been there done that'...
