I know we talk about the loudest plane or jets we ever herd, but let's break it down to wide body's. For me military wise, it has to be the C-5 Galaxy, but civilian 747 classic with PW
JT9 are hard to beat on noise, but a MD
-11 do not fall far behind. There some Russian wide body that I think use low by-pass engines, so they should be able to beat a 747 classic easy. So what is the loudest wide body you ever herd?
