B-1B crash in Montana with U-2 overhead

Interesting that a NASA U-2 has been circling above the Montana/Wyoming state line for over 2 hours now. Is it possible crash site is not well visible on satellite and needs to be secured by a U-2 watch dog?

Can a satellite vector a predator drone?

It was probably just a convenience more than anything, it was more than likely the closest aircraft available for good aerial photos of the site, rather than the time and money retasking a sat to be over it.
