I hope to see this in FS2004 someday. There is a 7E7 Addon in progress (I think) for Orbiter Spaceflight Simulator. Though it is a space simulator, Orbiter does have a ton of atmospheric flight addons. Though the atmospheric flight is not as realistic as FS2004, because it is a space simulator, you can still enjoy flying some great airplanes too. So until there is an addon for FS2004, and I hope that is soon, I can still fly the 7E7.
