So you thought you knew it all. Well think again because the world has one more secret to reveal. There is a flight simulator in Google Earth. That's right. And it's very realistic. Choose from one of two planes - an F16 Jet or SR22 propellor plane - both incredibly difficult to control. Or for me they were. To find these hidden treasures simply download the latest Google Earth and press Control-Alt-A, if you're using a PC, or Command-Option-A, on a Mac. You can take off from virtually any airport in the world and try and fly to new destinations using the complex controls. I just managed to get into spins, feel sick and crash but I'm sure with some more persistence you'll earn your wings.
