Well it maybe what Salty54 said. It happens also with B-29 and B-29 Silverplate sometimes (most times the cockpit loads fine only a few times game behaved like described above). After picking another aircraft and then returning to B-29 (without restarting the game) the pit loads. It was so since I installed UI1.1.

And it happens in QMB, so the problem with mission file is not likely.

However I never noticed it with any other aircraft in game.

Hope this helps.
