*** Posted by RUN *** I have only played Falcon 4.0 a couple of times, but I would say it is probably the most realistic sim available to the public. It is actually a little easier flying the real thing ;o) Especially formation flying (Air refueling), but that may be because I was using the keyboard and didn't have a good stick. The oxygen hose from the helmet hooks up to a hose in the jet. Regards (Run) [Hello military pilots! I keep playing Falcon 4.0 and keep wondering-how close is this simulation to reality? If any of you ever played the game please answer! And something else..the oxygen mask is on the helmet right? But when you get on the Falcon where do you plug it in? Thanks for your attention!!!]
