Eventough I do not think I have seen a Concorde in person, I herd them on TV
and on the web, and yes they was loud. I have herd a un hush kitted 707 and bother, I thought 747 classic and 727 was loud. I have not herd any airliner (except an Evergreen International DC 8 62 and a Canadian 737 200 that came close, but it is rare for a 737 even a 200 model to get that loud) that is as loud as a 707. I just wanted to know how much more noise did a Concorde make paired to a 707?
