From: munnari!vaxa.uwa.OZ.au!G_AHRENDT@uunet.UU.NET >All SR-71s are two-seat aircraft. As were all YF-12s. A-11's, A-12's, YF-12A's are 1 seater aircraft YF-12C, SR-71A's are 2 seater aircraft SR-71B's, SR-71C are 2 seater aircraft with raised rear cokpits >I have some beautiful pictures of the two NASA Blackbirds in flight >together. Both two-seaters. In fact, one of my photos is autographed >by the _four_ crew members. Strange, according to my information NASA used 3 Blackbirds : 60-6935,60-6936 & 60-6937. 935 & 936 being 1 seaters and 937 being a 2 seater. Stating that the YF-12C was built with a longer fuselage ( in comparision to the YF-12A ) to include a second cockpit, thus indicating that the YF-12A's were 1 seaters. Are you certain that the photo of NASA 935 is a 2 seater? >The two NASA aircraft were 935, a YF-12A, and 937, a YF-12C. I >believe, on the basis of no reliable information, that the difference >between the YF-12 and the SR-71 _airframes_ was the engines, but I >don't really know. The NASA aircraft didn't have any of the >recconaisence (sp?) equipment, of course. The YF-12A in comparision to the SR-71A had the chines cut back to clear the nose radome and the nose is flatter, to increase directional stability folding center-line underfins were added as well as 2 fixed stub-fins under the nacelles. >The YF-12A is at the Air Force Museum, where you can see it up close. >Two seats. What SN is in the Museum? You seem to be very sure, i hope you can enlighten me on this.
