Almost all of the incidents described in the preceding links involve the use of illegal drugs - some of which were alleged to have been used IN FLIGHT!!!! 1 or 2 of them involve alcohol, in collusion with some other general stupidity or external factor. None of the 'reports' mentioned offer any evidence of how determnations were madde of blood alcohol / drugs content were measured. The word 'probably' is used an awful lot.
I put it to you that my (modified) statement still stands.
