That mus indeed have been impressive, Wayne! Judging from the nice picture you posted the cockpit must have been nearly 20 feet above the ground, what a beast that was: her foldable wing panels cover half a tennis court..., and yes, she really is a magnificent sight. As Brian pointed out this is definitely one of the best examples of "form follows function" in the history of engineering.
I lived in Barstow, CA when the RB-70 was flying. One day my brother and I skipped school and had a nice day riding in our dune buggy. Then the stuff hit the fan... contractor chase plane hit the tail section, plane crashed, ejection canisters and chutes falling.
The area was cordoned off very quickly and we had some explaining to do!
I made a special effort to see the XB-70 at the Air Force Museum a few years ago.
Great to be able to still see it in-person. It was a little bit scuffed-up.
"Compression Lift".... a successful physics experiment.
A big challenge would be taxiing it around. You would need to be out over the grass before you make your turn so that you don't cut the inside corner and drag the mains through the weeds. It was something we had to be careful of on the 747 but the XB-70 is even further out.
