When did they stop making the 800ER? Or, is the 800ER now the standard 800? When it first came out, there was an 800ER. I like the 700 and 800 myself, but the 900ER has a neat look to it, if even a pencil look :S.I guess you're right, the 800 and 900 are really hard to tell apart. All carriers should do like Alaska, and put it on the nose :(

There never was a production 800ER. The 900ER has options that can be found on a 800 body though. The 900ER's extra tanks are a configurable option on the 800BBJ. The redesigned leading edge and flaps as well as the two position tail skid on the 900ER are available on with the short field performance enhancement program.

900 fuselage is same length (and basically the same) and the 757-200. In fact the 757 fuselage line was being transferred to Wichita (Now Spirit) before they cancelled the 757. Fuselages out of wichita travel by rail (as well as 41 sections for all the current Boeing models). Sometimes they show up in Seattle with bullet holes in them :) Must be some interesting folks living near those tracks.

Hm, well the smallest 57 is at least five meters longer than the longest 37, that's for sure. And carries a few dozen more pax too, well depending of layout obviously. Not sure about other fuselage aspects.

The 757-200 is 155ft 3in long. The 737-900 is 138ft 2in long. So the the 757 is 17ft 1in longer, or about 3m.Hiram Hunt

Of course, which model you're in has an impact on a takeoff variable. Anyone care to venture a guess what it is? :(

You'd soon see when you pitch up that's for sure :( John Ellison

The ng has a very beautiful long slender wing. the classics have the old 200 wing. It's very short and stubby.

John wins! Basic geometry means that the longer models have a more restrictive pitch limit on rotation to avoid a tail strike. The same principle applies to the A320 family, though they might have some sort of FBW protection to prevent a tail strike, I'm not sure...
