Everyone is familiar with blue-screening kiosks and travel information displays, but this one was pretty new to me. The route display on this Air Algerie Airbus a330 was visibly experiencing some disk issues. (They rebooted the aircraft in midair, everything was fine after).
Still, the thought of flying around in something that is controlled by
Redmonds' finest scares me even more :-)
[Note after 53000 views: No, this is not a normal Linux boot sequence. See the original sized version for the gory details. Also it got stuck here for a long time (~10 mins) until they restarted the app. And as some pointed out below, I doubt very much that up until this point off-the shelf OS'es are used for anything mission critical. Duh.]
