Possibly, but will our very weak (relatively) radio source be detectable
among the myriads of strong radio sources? Will they even be looking?
Will they care? They may not even exist on a planet that has an atmosphere
that is particularly transparent to radio waves. We are making large
assumptions regarding the motives, interest, and capabilities of a
hypothetical advanced race. Even a distance of 50 ly is prohibitively
large based on our current understanding of physics. They might not even
be interested in making any type of contact with us, to the point where
they go out of their way to avoid us even assuming they have developed
strong interstellar capability. A race that was simply looking for
resources in other systems might prefer to avoid us to prevent possible
contention. Consider all the unoccupied yet equally accessible star
systems available.

Then again, the situation could be that we are the most technologically
advanced society in our neck of the woods. Within a 100 ly sphere, this is
a very plausible possibility. IMO, our best odds of finding ET
civilizations is to go out and look ourselves.

I was presuming that the stealthy craft were of super-advanced alien
origin. Of course our stealth aircraft have much more limited capability.
"Stealth" as currently applied means hard to detect via electronic means.
As for crashing, "stealth" aircraft have very ordinary airframes and are
subject to the same laws of physics as any other aircraft.
