Driving on 10 cm thick icy slippery wet and snowy roads in Iceland : check! When you're driving on route  towards the South east, with the ocean on your right, the glacier with its unpronounceable name standing proud on your left, and then suddenly in your rear-view window you see a car sliding from left to right before completely sliding off the road then it's time to slow down. Really!
Finally after two days we managed to find The Plane!
An abandoned U.S army plane in hidden away in the depths of Iceland...
For all the travelers, seeing the landscapes during winter time is completely different of summer time, if you can, you must come back! :)
