JFK was on 26000, the single 707-320B (VC-137C) delivered in 1962 and then used as Air Force one. The other one would have been one of the 3 USAF 707-120Bs (VC-137B). They were delivered in1959 as turbojet -120s and later re-engined with JT3Ds as -120Bs like most early turbojet -120s. 26000 was replaced as the primary Air Force One aircraft by another 707-320B/VC-137C (serial 27000) in 1972 but 26000 remained in service as a USAF VIP aircraft until it was retired in 1998 after 36 years service.
