You might be thinking about this though. During the LIBERTY attack 7 months earlier than PUEBLO planes were launced and on their way to help Liberty from a carrier but were recalled inflight by Pentagon in a not so polite wording as I understand it. They never made it and were ordered back to the ship. The LIBERTY attack followed by the PUEBLO attack makes me wonder what LBJ had gotten himself into though.
Very painful - we could go on on this - suffice to say that LBJ was a mess and is still to - to this day.
