Continuing with my “connect-the-dots-but-skip-quite -few-in-between” thinking that spawned my bot suggestion in the first place, another far-out area that Microsoft could explore in MSFS is adding space vehicle flying. Perhaps the different companies that produce space or near-space vehicles of some sort would jump at the chance to collaborate with Microsoft and Asobo to include their vehicles in such a “flying machine” category in the sim. The dot connection is that undoubtedly these days flying a near-space plane or going into orbit in a space vehicle is a largely bot-controlled endeavor. And Microsoft and Asobo certainly have the data to simulate views of the Earth, 10, 50, 300, 22,000 miles into space, etc.
One could go by the rule that, HEY, this is a sim and as such should provide only common, popular real-life flying machine simulations to the masses. But somewhere after helicopters and gliders, maybe there’d be room for the inclusion of more futuristic, even imaginary vehicles. Maybe even now NASA has enough data to simulate flying anywhere in the solar system and one could just set one’s capsule on autopilot as you coast 1 1/2 years or whatever it is to Mars out of Earth orbit, etc., before you do your Seven Minutes of Terror touchdown. 
Basically, I think there should be room to try out on users simulated experiences that are not entirely the cut-and-dried, down-to-earth variety (literally and figuratively). AIA, if there’s already a couple of space vehicle threads somewhere here on the forum…
Edit_Update: Found one such space vehicle wishlist: Space Shuttle Mission Pack for Flights to ISS and back
