One thing Im curious about is what is classified as a "reboot" of the plane? It it is parked over night are all the systems shut down and restarted the next day it is put back in service? Does it sit "running" in some sleep mode? Last time I checked a plane cannot(practically) stay airborne for 51 days. Is the reboot a pain in the ass 5 day procedure? there are too many unknowns to sound alarm bells.
