Believe me, they still have an ultra high speed delivery/recon vehicle.
Sattelites are not always in the right place when you need them.
No, but they do a good enough job, and you can get all the same effects.
There's no need to build and fly a recon jet at this point, most of the photo's you see on the news are satellite pics in respect to locations.
As far as I know, I don't think we even use recon jets anymore (strict recon/spy only). I'm sure bombers and other jets may and can do dual roles, but nothing that is single specialty spy plane stuff.
