Sideways moving Simulator
4 Greens:
Your post #82 reminds me of an L382 Hercules Simulator that on an ILS approach to Denver USA, used to get a quirk and transfer itself (display) due north at a great rate of knots straight through a mountain. It was a hell of a relief as you came out the other side!
This was quite awhile ago and certainly made an impression.
