My father works for GE and had worked on those engines before the whole thing got cancelled. My question is how big a difference is there between the A and B? I know the A was supersonic and the B subsonic, but how about payload, range etc. What were the technical reasons for changing the B to subsonic (or was it all just political/money)? Does the B1 program suffer a lot from getting only B's instead of the original A's. To stretch things even farther, how different is the B1A from the original XB-70 (range, payload, speed)? Were any of the results from the B-70 program used in the B1, or was all that lost? Why was the B-70 cancelled (I remember a crahs but assume the cancellation was politics). Thanks for the information. >>>Bill<<<
