Trog.....that WPB Steamer is the original American Airlines Training Corp 76A Sim is it not....vintage 1980?
It had some interesting glitches in the software....like a two foot difference in the taxiway and parking apron in places....which was good fun to drive either "into" of "off of..." while taxiing around the place.
The Great Wall of Pahokee was another thrill....some very odd things happened when one flew into that and survived on the other side. It did reinforce the concept of "Fly the Machine!" Students thought we were doing some thing to them when in reality it was the Sim doing it all on its very own.
