Somewhere, I have a photo of that very airplane at the U-H Center, complete with the bugs on the windscreen from when they flew it there and parked it.

The engines for  the new 777X have a larger diameter than the fuselage of the 707.

( I think the 17" wheels on my Boxster have a larger diameter than those 707 engines. /s )

I don’t know if that’s the GE9X engine above, but damn those 707 engines look like hot dogs!

I wonder if there are any 707s (or DC-8s for that matter) operating anywhere in the world with the original turbojets. any that I’ve seen have the later low-bypass turbofans.

oh, and just for some perspective:

Probably not civilian ones, but I believe the E-3 still uses a low-bypass turbofan in most cases:

IIRC RAF and Saudi ones have newer high-bypass engines instead:

At least some E -8s have  an upgraded, but still-low bypass engine setup:

Frankly it’s weird that we haven’t re-engined them, especially given that we did do the KC-135s. I believe the thinking was that E-10 was right around the corner, so why bother, but with the E-10 cancelled you’d think they’d have quickly moved to modernize the aircraft it was supposed to replace.

Found this photo I took, still can’t find the bugs-on-the-windshield photo.

The scallops on the engine nacelle actually function as a sort of hush kit to make the engines even quieter.

My research kept swapping from fan size to total size to ????
