This reminds me - not long ago I was on a trans-Atlantic flight and I was mindlessly poking around a touchscreeen of an in-flight entertainment system. A right-click menu poped up, a typical browser one. It had a SaveAs option, so I went on, looked around and the file system had typical *nix structure with /usr, /root, etc. Then they started the take-off prep and rebooted the while thing. So it gave me a minute or so. Once it was back up, I killed an hour trying to reproduce the menu popup, but couldn't.

So next time you find yourselves on the plane, bored - keep this in mind, try and reproduce :)
