just to clarifies some of the event
when the captain saw the U/S cdu he left the plane with all the crew leaving the passengers onboard without calling the dispatch.he went straight back to the hotel.
in 30 min the problem was solved by the technicians
the incoming crew brought back the plane after a minimum rest with the previous crew on board
only the captain was fired in this case.when he arrived in MXP
i agree that blue pan is not the best one but you can't start that kind of threat without knowing the facts.
