".50 cal sniper fire from ULA’s roof?

.50 cal not needed (thought it would definitely do the trick). Pretty much any scoped rifle firing a centerfire round (well, maybe not 5.56.... :^)) would probably do the trick. A mile is nothing, and the target is really large wth many vulnerable points.

A mile is nothing, and the target is really large wth many vulnerable points.

I wouldn't characterize a 1700 yard shot as nothing, but the target is much larger than a human. However, if you want enough energy left to do any damage, you're going to be shooting either a .50 BMG or a .338 Lapua.

Longest recorded sniper kills.

A mile of lost velocity . . Nope. If you’re going to do it why wouldn’t you have a .50 cal?
