Okay, then... am I crazy for noticing jet engines on airliners are significantly larger these days compared to 20 years ago? You did say larger fans. I always thought I was crazy when I noticed planes were quieter until Neil degrades Tyson mentioned it.

You’re not crazy. The engines are bigger and quieter.

Definitely not crazy, and the engines are getting larger. The 737 MAX issues stem the packaging issues of putting larger engines on an airframe that wasn't really designed for them.

The largest commercial jet engines are actually about as wide as the fuselage of the 737! The first jet engines were less than a meter wide.
