It's an easter egg that the game developers put into the game for your enjoyment. There are several others ingame you need to explore the interiors of certain aircraft to find some of them and of course there's the squirrels,they have cameras and use them for your protection. HTC has put a squirrel in every third tree,if you find 1 take a screenshot and submit to HTC,rumour has it there's some kind of prize involved! is there a list of the easter eggs?
