The Truth Behind Boeing's Billion-Dollar Supersonic Flop

The Boeing 2707 was going to be America's supersonic airliner — bigger than Concorde, faster than Concorde, built from titanium to fly at more than twice the speed of sound. By March 1971, the US government had put $868 million into it: about $7.2 billion in 2026 dollars. It never flew. Washington had been promised every dollar back by the 300th sale. Not one was ever sold. This is the truth behind the Boeing SST, the "American Concorde": how a $4.5 billion program was sold to Congress, the two reviews that said no, the swing wing that failed, the sonic boom test that brought in complaints, and the 51–46 Senate vote that killed it. Then the part that matters now — the 1973 ban on supersonic flight over the US that it left behind, and why that ban is finally being rewritten as NASA's X-59 and Boom Supersonic chase the same dream.
