These all seem very bizarre questions to me, kinda like asking if this was because they forgot the pickles on his big mac.Did some Germanwings flight attendants feel resentful that they were not permitted to take breaks in the cockpit or flight deck, with the pilots? Did Lubitz have antagonistic feelings about the idea of armored cockpit doors? Did Lubitz intend to hurt the business of Germanwings?
Did Lubitz resent the bargain-hungry travelers who utilize discount air lines? Is it safer to fly full-fair with adequate pilot pay and benefits?
