It's been nearly two decades since supersonic commercial flights last shuttled passengers across the Atlantic Ocean. Asthat's been enough time for companies to start examining the feasibility of supersonic commercial travel again.
The original aviation icon that once flew scheduled commercial flights at twice the speed of sound: the Concorde. The Concorde was supposed to break the United States' hold on commercial air travel, but in 1974, 12 years after Britain and France signed their agreement to build the plane, its economic viability was already being questioned.
Morley Safer reported for 60 Minutes at the time, "For as beautiful as Concorde looks as it blazes through the sky pushing 1,400 miles an hour, the economics of commercial aviation have made it a $2 ½ billion white elephant and no airline really wants it."
