The charge sheet in Cyprus said the two pilots were unfit to fly the aircraft and that Helios knew or should have known about this
Confusing the meaning of the intermittent horn did occur before Helios.Several times.On paper, its a surprisingly simple and basic error for a flight crew to make.But it happened.The precedents mean the crew can not be characterized as "unfit".Pilot error is pilot error.And they have already paid the ultimate price.We should leave it at that.I studied the case and saw no real indication of company malaise.It was a one-off.A freak accident.
