Also, wasn't part of the reason the USAF scarfed up so many used 707
and 720 airframes back in the '80s was for replacement vertical stabs
for the KC-135s? Or was the folding stab only implemented on the
367-80?


The USAF bought the retired airliners for the engines. The JT3Ds replaced
the J57s in AFRES and ANG KC-135As, converting them to KC-135Es.
