757-767-777 DNA: What's in common, what's different?
I know all three share the same cockpit(section ahead of
'41'). This is why the 757's front end looks bug-eyed,
the 767, just right, and the 777 - slightly squinty, widening
aft to accommodate a nearly 747-wide cabin.
Secondly, the vertical stabilizer('tail fin') on the 767 looks
disproportionately tall, and correspondingly undersized
on the 777. Looks like the same sized fin was just
transferred to the later, larger 777. 757's stabilizer is
unique to that type.
