yes it is expensive but you get exactly what you paid for
Just because it has "Aircraft" stamped on the side doesn't mean it's not subject to failure, you don't get exactly what you pay for, reliability, A320 written off because the automatics wouldn't let the crew flare for landing, A330 automatics in Western Australia which took the crew and pax on such an exciting ride that the Captain retired with PTSD (occurred due to the combination of a design limitation in the flight control primary computer software), 777 again in Western Australia where automatics took the folks on an exciting ride (the crew experienced a situation that had previously been considered not possible).
