Pretty much nothing was shared between the B-70 and the SR-71(the designs are completely different), the SR-71 was an outgrowth of the A-12 program, although the SR-71 designation does come from the short-lived B-71 designation that the A-12 follow-on acquired when it was proposed as a replacement for the already long-cancelled B-70 (The B-70 was cancelled in '58, the A-12 didn't fly until '62 and the SR-71 program began around that time). Interestingly, the SR-71 tooling was destroyed at the direct orders of Robert MacNamara, quite possibly due to the possibility of the F-12 program replacing the troubled F-111 program for a USAF interceptor (A role which was eventually filled by the F-15, not the F-111 whihc proved unsuitable for almost all of its designed roles). -Adam -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
