The old 146 sim used to show
The red screen of death and motion stopped.
717 Sim, crashing sound, can't remember the visuals.
The best visuals (non-crashing) that I've experienced were in the YSSY DH8 sim. Cars could be seen driving past the airports, other aeroplanes, buildings, mountains, etc were very realistic. Flying under the Sydney Harbour Bridge was a hoot, except the visuals had poor detail of the underside of the bridge.
It was known to be left in the car park at YBBN, or on a hill top overlooking YBCS or YLHI, from time to time.
