I think the A-12 first flight was in ‘62, and Kelly Johnson told me that they had finalized the configuration in late ‘59.the XB-70 and A-12, both of which flew in 1964,
Sort of. The Douglas DC-8 first flew in 1958, but it was 1960 when they set out to fly one at supersonic speeds to prove the aircraft would survive a flight at that speed. With the help of a steep descent, they reached and held a speed of Mach 1.01. However, the speed caused enough load against the stabilizer that they were not able to recover from the dive until the pilot pushed forward on the elevator to unload the downward force on the stab so that it could be retrimmed for level flight. The pilot also mentioned that as they passed through transonic, he said they saw both ailerons deflect upward a bit.Didn’t the USA have a commercial jetliner capable of breaking the sound barrier in 1958, years before the concord?
And unlike The limited nearly handbuilt production run of the Concorde I think they built over 500 of them.
The Celera seems like a great accomplishment, developed with their own money so far. But with a pusher engine they could easily have designed it with great visibility forward. There isn't any. The pilot can see up and just a little to the sides. The Lear Fan was a lot better in that regard. Well, most jets are, too.
I’m not too sure about that. I’ve seen sports cars that look like they have no visibility (either foreword, backward or both), yet when you sit in them, you find out you can still see out.The Celera seems like a great accomplishment, developed with their own money so far.

Unfortunately, Opal perished when his plane broke up in flight.AMT Lynx turbojet 350 lbs static thrust weighs 40 lbs...... is going to be used in the Project-X Reno Pylon-racing competitions......
Hey, why not install it in a simple carbon-fibre Opal Facet ? Ultimate in ELEGANCE & SIMPLICITY!!!!
Since Opal Facet is a bit small, just scale up by say 150%
Although the A-12s were often flown by Air Force pilots, they actually belonged to the CIA. The Air Force version was the YF-12, which was replaced with the SR-71.that would be the XB-70 which never entered service and the A-12 which only served in one exclusive arm of the military. So, exactly the same as Concorde?
