Sorry, that was supposed to be "spend".
Fighters usually take off in groups of two and four, and the typical flight line is right up against the runway. The sound is so obnoxious you can't hear yourself think, and it's one right after another. Another engine noise that is notoriously frustrating is the T-37, or Tweet. So called because of the unique sound their centrifugal-style compressor jet engines make. We had a whole squadron of those divert to Barksdale AFB when I was stationed there in the 90's. Man I was glad when those things left.
Anyway, not hating on our fine American machines, just reminiscing in a way.
