There was a screenshot posted by Oleg last year in one of his updates which may answer the question.
I couldn't find it on this forum, but fortunately Foo'bar has kept them all for us.
Here is the link to that screenshot, in the October 2009 screenshots;

The question is, is that a screenshot of a pilot sticking his head out of the cockpit or is it an external camera shot?
