Oh, there's one of these BS stories every few years, it never happens.
On the Aerion: "Backers predict it will enter into service by 2020". Riiiight. Eight years. It was eight years from the first orders of the 787 to the first deliveries. It'll be slightly more than eight years from the first orders of the A350 to the first deliveries. That's for a relatively conventional airliner, built by a giant pre-existing team of engineers with expertise and facilities to build airliners, and with sufficient money in the bank to fund the building of an airliner.
This is a supersonic jet to proposed by some aerodynamics consulting firm in Reno. It's no closer to being built than a jet sketched by my eight-year-old nephew.
