Answers: Its problems be solved! The first one was vile, the second one had singular a few snags and the third one was going to be virtually foolproof. It would have be cheaper to manufacture per plane than the SR-71 while competent to fly nearly as high and swiftly with a payload (pretty perfect for a plane that weighs more than a B-52). It still have the best lift-drag ratio of any manned aircraft ever built.
Unfortunately the concept be obsolete contained by the face of ICBMs and SLBMs. I assume it could have stood a casual as a bomber (it had almost the dramatization the SR-71 had and IT be never shot down). With stand off missles it would own been invincible into the stealth age (sure you can see it, but what can you do roughly it?)
But with the loss of the second prototype and scapping of the third it never have a chance to shine (except for going down contained by history as the most expensive aircraft in history, until the B-2 took that honor away).
I still ponder it is one of the coolest planes ever made. Hope to make it to Dayton sooner or later.
The only unsolved problems near the B-70 was it's cost and it's inability to undamagingly enter enemy airspace after the advent of modern surface to nouns missiles. The two Valkyries built proved that the mach 3 wave rider concept design be possible. By the time the first prototype was flying it be already obvious that despite their dignified altitude and speed they were adjectives to attack. When they were built the credo be "higher and faster, but near the advancement of radar and surface to air missiles it be decided that "low and slow" begin to be the way to evade radar and enter rival airspace. I've read that the six engine bomber was so loud that anyone handy during takeoff could become physically unwell from the noise even. I'm talking throwing up sick as a result of the intensity of the nouns. If they had gone into production they could never enjoy staged them anywhere near any populated areas. I've see the surviving example at Dayton a couple of times. It's pretty much the star of the show there. It's really a verbs to behold.

there is no solution for incidental midair collisions when flying close formations of such different types similar to a strategis supersonic bomber and interceptor plane.
