Science

back in the day...at Greater Pittsburgh Airport which was one of a few "inland" sites that the Concorde could actually land at the time.
They even had commercials trying to convince people of the advantages (Pgh had a lot of international businesses then). But when questioned about the noise, the ads stated that it was "only 20 db more than a 707 landing or taking off."
Might have even worked had not an environmental group explained that the db (decibel) rating was logarithmic rather than linear. An increase in 10 db doubles the sound. 20 db is 100 times more. So, when the residents discovered one operating Concorde would make as much noise as about 100 707s taking off or landing, the idea was scrapped.
