a pilot that thinks he knows everything = a dangerous pilot
a pilot that ignores no go defect = a dangerous pilot
likewise
an engineer that thinks he knows everything = dangerous
an engineer who ignores a no go defect = an idiot.
the only thing is i honestly think that a dangerous pilot is more likely to take a no go aircraft than an engineer would be to release one
as for a pilot that doesn't want to accept an aircraft that has been released... ok explain why and if you still don't accept it... well then i'm going for coffee
as for a pilot that thinks an aircraft is servicable when its not... i park my car, tug,or anything that i can behind it so it cant depart... take the key and...... then i'm going for coffee
