i know its a controversial post but its right for more reasons as well. Concorde was economically advantageous as long as fuel represented a small percentage of operational costs it launched in 1973 during the oil crisis and all the way through the OPEC embargo, and almost immediately became the most expensive plane any airline could choose to operate.
Airlines also had to contend with when and where to execute supersonic flight, as a boom over a populated city would immediately draw negative publicity. pushback in some cities in europe reduced the Concordes routes and speeds significantly in 1976
Concorde produced nitrogen oxides in its exhaust, which, despite complicated interactions with other ozone-depleting chemicals, are understood to result in degradation to the ozone layer at the stratospheric altitudes it cruised. while concord was a small fleet, 500 of them could become an ecological disaster.
Concorde's high cruising altitude meant passengers received almost twice the flux of extraterrestrial ionising radiation as those travelling on a conventional long-haul flight. the flight deck had a radiometer and an instrument to measure the rate of decrease of radiation. If the radiation level became too high, Concorde would descend below 47,000 feet. to my knowledge we still havent produced a SST that solves the radiation concern.
