Hi all, just found this on the net, its an online flight sim, ok so its not as realistic as Flightgear but it does use google maps so the maps are accurate all be it flat with no buildings (it does have hills and mountains) i have just flown from my house in North Kent around the Kent coast to Hastings and then north to the M25 and followed the M4 to Wales and beyond, I think it covers the whole world, good fun if you want a chilled out flight without complications.
