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?

I remember when the 747 first started flying; I was in Amsterdam at the time, in 1971, and you could hear the "buzz saw" noise from quite a distance. That is when these aircraft still had the blow-in doors at the front of the cowling, as seen in this early photo:

I remember seeing a rather spectacular takeoff of a UPS 741 from SDF a few years ago. She was lifting off from 17L (8500 feet) and got airborne right over the numbers at the departure end. Cleared the blast fence by about 30 ft and SCREAMED over the UPS parking lot. I was so thrilled by this takeoff that I screamed in excitement as she blasted over. Despite there being about 20 people within earshot, nobody heard me over the aircraft. And to boot, I counted at least 7 car alarms going off after she passed over. This is to date the loudest widebody takeoff I ever witnessed, not to mention my personal favorite.
