The Concorde, the world’s first real supersonic commercial jet, was perhaps the most exciting plane ever produced. But it failed at being an economically viable proposition, an absolute must for any airliner. This video by Vox explores the legend and the reality. Scalability is the term that best explains the Concorde’s demise. Restricted to transatlantic routes because of its sonic boom, with poor fuel economy in an era of skyrocketing energy prices and limited passenger capacity, the airplane never went into mass production. Consequently, it never made sense for the manufacturer to invest in upgrades or successor models. British Airways and Air France pulled the last ones out of service in 2003.
But the mystique and glamor live on. On a personal note, back in the day I lived on one of the approaches to JFK airport. You always knew when a Concorde was overhead, and looked up. It was that noisy even without the sonic boom. But what a sight!
