I wonder what kind of Mack Truck 18-wheeler drives? The rest of us have ACARS, and it is difficult to cheat, unless the park-brake is released early to show a block-out before the actual event.
Anyway, I think this is a more serious matter, as the crew were apparently penalized for insisting on a baggage reconciliation after some passengers had deplaned themselves in Karachi.
For whatever reason, this led to a confrontation and standoff with ground staff, and a long delay before the aircraft finally left.
Maybe in a Union environment, the crew would have been better able to explain their safety concerns about unaccompanied baggage, etc. As it is, a dangerous message has been sent. It also seems ironic that this happened in that oasis of Peace and Tranquillity, OPKC!
