Boeing six engine jet bomber which entered service in 1951 and lasted until 1966. It was the backbone of SAC's(Strategic Air Command) deterrent force until the early sixties. It is also the direct ancestor of the B-52, KC-135, and the indirect ancestor of every modern jet transport except the Concord. One hell of an airplane. It was called the Stratojet.
The B-47 had only a three man crew.

A word someone or some people might use to try and make someone feel left out.

mean guy: *roffles* I'd never tell someone like you.
