Where 757 fits
Why 757 is special
Its unusually powerful engines and long wings let a single-aisle aircraft fly transatlantic routes too thin to fill a widebody. Nothing has quite replaced it, and the gap it left is a recurring topic in aircraft programme planning.

Related numbers & connections
Boeing developed the 757 and 767 together with a common cockpit, so pilots could fly both on one rating. One is a narrowbody and the other a widebody, which made the shared rating unusually valuable.
