Official Boeing photograph comparing the B-17 Flying Fortress bomber and its successor B-29 Superfortress bomber, circa late 1944. Interesting comparison!

Do you have the figures for speeds, service ceilings, bomb loads and ranges. I'll bet the differencs are even more impressive.

According to this source, B-29 had a lot more speed, less service ceiling (hard to believe that), lots more range, lots more weight, not much more bomb load.

Here's an interesting comparison

B17

Max Speed - 249 kts

MTOW - 65,500 lbs

Range - 1700 nm

F15E

Max Speed - 1500 kts

MTOW - 81,000 lbs

Range - 2000 nm

I've always had a soft spot for this one so we'll throw it in the mix!

And don't forget - this thing flew off a carrier!

Wasn't the F111 orginally supposed to be a carrier based arcraft?

I worked on and crewed on B-29s and B-50s when I was in the Air Force at the end of the Korean war.
Wonderful airplanes......as I recall the difference was larger engines on the 50.
