"Can you just imagine a LH pilot acting as cabin staff in order to break a strike?"
The fact is Studi, the actions of BA pilots had nothing to do with the perceived financial state of the airline as perceived by a few BALPA reps, but a general policy of appeasement to maintain their status quo. Appeasement as Winston Churchill said "is like feeding a crocodile in the hope it will eat you last"
Appeasement as a strategy has never worked for long historically. Walsh can see that this relationship has run its course, and he has turned on his pilots in an act of filicide.
