Rainboe,
There you go, twisting my words AGAIN.
I said
If the fin of a serviceable Airliner can be ripped off purely by Pilot cockpit inputs, then I for one don't think that Airliner should be flying.
The B737 incidents you are on about IF TRUE, were with an UNSERVICABLE Airliner/s.
Just as was the case I still feel with the AA A300 out of JFK.
I still honestly think that if any serviceable Airliner (that is no faulty components or weakened structure) can be brought down PURELY by mechanically allowable (whether normal or not) Pilot inputs then it should NOT be flying.
