Now that is about the most constructive solution I have read so far but I do wonder how many of you out there would actually have the balls to do that.
More years ago than I care to remember, that was the only way that the Red Arrows (when they flew Gnats) could go anywhere in Europe due to their lack of range and inability to deal with the vagaries of French ATC etc.
Their answer was to climb to F310 or thereabouts and then go "speechless" until it was time to come down again.
Worked like a charm.
