I uploaded a set of 757-200 pics from SFO last year which all show the aircraft at the 01R hold in full profile. What struck me was the difference in the fuselage cross-section forward and aft of the wing. I've not noticed this on any other commercial airliner (ok...we'll exclude those with obviously different shaped fuselages) and wondered why the 757 was built this way.

The cross section immediately forward and aft of the wing is exactly the same on the 757. The constant cross section extends from Station 440 (the 41/43 section join) to approx station 1480 (just aft of the aft cargo door). What you may be noticing is the difference between wing-to-body (WTB) fairings forward and aft of the wings. The WTB fairings are composite fairings attached to metallic secondary structure, external to the fuselage and doesn't have any mpact on the fuselage cross section.

Thanks for that info Duncan.
Ok...maybe cross-section was the wrong term. It is the depth that I see as distinctly different.
Granted the wing-to-body fairings fore and aft of the wing are different...but if you take the edge of the window and resize until it is level with the rear fuselage...there is a very obvious difference in the forward fuselage depth.
Although I see it mentioned that other Boeing aircraft share this feature I don't recall seeing such an obvious difference.

Looking at Delta I see what you mean-- the top of the bare-metal seems to run right at floor level, but the apparent depth of bare metal is greater aft of the wing than forward. But I assume it's some perspective effect-- can't believe it's really deeper aft.

Timz - are you sure of that? I am certain that the 757 has the same fuselage cross section as all the other mentioned Boeing narrowbodies (though if you give me some evidence to the contrary, then I guess I will be proven wrong, won't I?).
