I did sonic testing on the KC-135R, a high performance re-engined military version of the Boeing 707 -- actually the military version came first. This happened in the early 80's and those refueling tankers are still flying, just like some of the Boeing B-52s, a design which goes back to the 50's.

The USA has had several bomber upgrades, the B-58 "Hustler", the F-111, the B-1, the B-2... None of them have outlasted the B-52. Still flying.

As was the "Leper Colony" in 1962, that is until it hare-lipped everybody on Bear Creek.

the NO STEP is the rivet line to the aft or fwd upper skin to the wing spar trailing or fwd edge, but looks like the aft rivet line...............................
