Someone refresh my memory: Besides the digital glass cockpit, carbon disc brakes, etc. . . isn't it true that the classic airframe and its systems are at least 80% identical? Some classics even have -400 engines [CF-6-80] and faired (-400) wing roots, notwithstanding that the -400 wing is larger with 13 leading edge flaps instead of 12, but same parts, no doubt. And not to forget that Air Force 1 and Air Force 2 are classics, so I seriously doubt that Boeing would categorically
"no longer support the classic." All the best to you classic drivers [and F/Es] in the years to come.
