This has been a reality since Sputnik, it's not really a recent concern. The obvious solutions are:

- Test at night

- Test with clouds overhead

- Test indoors

Once the aircraft takes off or lands hiding it is easy. It's just for the few minutes that it's out on a tarmac that you have to worry about it being spotted.

One possibility is that this is a deliberate misdirection, there is no plane in that hangar or if there is it looks completely different from the one in the picture. The fact that so many people in this thread are going down the NGAD rabbit hole (a program which is barely fleshed out and nearly all of it is open for interpretation) may indicate that this is the path the US wants Chinese and Russian researchers to go towards in order to cover up the "true" path. I'm more willing to believe that than the possibility that they left a billion dollar aircraft out in the open with a publicly tracked satellite directly overhead. It's not like they don't know when Planet or other satellites are going to be photographing the base.
