From: bcsaic!vince@cs.washington.edu (Vince Skahan) I saw the tail end of the Wings last night on the XB70 and was interested in how it stacks up against some of the other aircraft that really got built... Can someone compare the range, speed, payload, etc. of the XB70 vs. the B-52, B-1, B-2, etc. ? -- Vince Skahan ARPA: vince@atc.boeing.com UUCP: uw-beaver!bcsaic!vince
