Re: Concorde, so loud
Absolutely the take-off noise.
A university mate of mine had a place in Heald Green slap next to Manchester airport. Most aircraft you quickly learned to ignore, Concorde not so much. It was hellish loud and also very good at setting off all the car alarms on the street. Not great when you are nursing a hangover from a typical student beer and curry night round Rusholme.
Engine-wise Concorde was essentially an Avro Vulcan with afterburners, and the Vulcan was already bloody loud to start with.
