My computer guru had a client that had the software & rudder pedals in his office & would fly the most realistic fake plane you could imagine. He had 1 program that was set up for a 737 stretch & you would think he was in a flight simulator at one of the airlines. He had some serious bucks in that set up. He had a friend who was an actual pilot that had flown stretch 737's & he would come over on days off & help him tweak the software & hardware he had set up. Between him & the pilot they bought or made a lot of the controls. Jaw dropping is an understatement when you walked in his office. The 50 inch monitors on the wall made you feel you were on the flight deck rolling down the runway for take off. Was only there a dozen times over the years & it was still not enough. von.
