I looked at the numbers awhile back...the GE
-90-94B's diameter is 134 inches, and the GE
-90-115B's diameter is 135 inches. 737-500's outer fuse diameter is 13 ft 2 in, or 158 inches. Data taken from the websites of GE
and Boeing, respectively.
Still, it's one big mf'ing engine.
Edit: the 737's interior cabin diameter is 11 ft 7 in, or 139 inches, so that's closer (but still bigger) than the engine.

I'm watching Jeopardy. The category is worst Madonna songs. "This one from 1987 is terrible".
