Has anybody heard of this?
It's called Shuttle: The Space Flight Simulator, it was made for DOS in 1992, and I absolutely love it!
Though then again I like a game where you essentially flip switches for an hour or so, then have to land the Shuttle using keyboard controls, so perhaps I'm just mad.
It's on abandon-ware sites nowadays, so if you want to you can all have a go yourselves, but if you want the lovely sound as seen in the video, you'll have to set up a Roland MT-32 sound emulator.
... Just thought I'd share what I think is a cool old game that nobody's probably heard of.
