But it is one hell of a gamble to travel that far and hope there is a gap in the cloud to get back down through remaining VMC at all times!!!
More people should think about that, as I've had the "pleasure" of controlling GA aircraft stuck VMC on top after a 400nm flight.....
And where do they try this? Oh, well inside the arctic circle offcourse!
A solid cloud cover and and 6000ft terrain below, is allways fun!
It has worked out "fine" for all, for now, but that's 99% luck in some cases.
