Hi ejc - afraid I've been around for a while. My only link with the aerospace industry was working on the staff newspaper for Hawker Siddeley Dynamics back in the 60s, so I didn't really get into the technical side of things. Oh and I worked for a press agency at Heathrow 1959-1961, so I remember the Comets, Britannias, 707s - and the Lockheed Constellation which I alway thought was one of the most elegantly shaped planes of its time when it was in the air.
Krissell has a fair point - if the noise factor could have been addressed, Concorde might have had greater popularity. I lived near Upper Heyford when it was still a USAF base and remember the roar produced by a gaggle of F-111s on the odd occasion they used afterburners for take off!!
