It's almost certainly Windows. What would you expect a DoD desktop computer to be running?

As you can see in the picture of the Predator cockpit so helpfully provided, it is definitely windows.

probably are... mission control at spacex has many windows terminals.

What does this have to do with SpaceX? They're not DoD and they don't fly drones.

They obviously fly satellites into low-orbit on contract for the govt. My point was control of expensive/dangerous things - by (or for) the govt with potentially dangerous sw.

I don't think the problem here is their OS, rather it'll be their network structure. So instead, perhaps that should be:

"Oh please tell me they didn't connect directly to the internet".

That's the sort of thinking that leads to a crunchy shell with a soft, chewy center.
