I think this plane is a DC-8, not 707, but I could be wrong.
The one in the picture at post 101 is a KC-135, which is a darned sight closer to a 707 than to a DC-8.
Sure looks like a KC-135 to me, and I thought those were 707’s.
Nope, it’s a KC-135, which I *think* uses the Boeing 720 airframe. The 720 was a 707 derivative, so the Stratotanker is basically a 707 one-and-a-half times removed.
I haven’t heard of any civilian 707s/720s ever converted to take modern high-bypass engines like the ones on that KC-135, but the DC-8 has had that done. UPS flies a bunch of old stretched-fuselage DC-8s that have had their original engines replaced with four CFM-56s, the same engines that power modern 737s. They’re quieter, more efficient, and still useful for hauling cargo cross-country.
Travolta’s 707-138B looks like it’s got the original Pratt and Whitney JT3D engines on it. I expect that thing lays down a smoke trail on takeoff that nothing short of a B-52 is going to match—those older engines were very sooty at full power. One takeoff and trans-Atlantic flight in that beast would probably leave a carbon footprint like Shaquille O’Neal’s size 22 foot!
