It had to be , how is it I have three books on the type , two here with different information but accurate .. good cross reference , the aircraft of the period , Marty's Big Roundie is powered similar engine but the Peacemaker had more powerful version of those engine , redesigned and just to finish ya off put four jet engines on the wings , even in the mid 1950 consider impossible to down by fighters ... even old Chuck Yeager said be a lucky shot to get one ... the old KC-97 tho the jets were added to help with the new Gen of jets with a higher stalling speed , amazing stuff !
