I found this article while I was looking through my inbox a few years back, and I didn't take it seriously. But I found yesterday that it 100% true; supersonic flight is coming back! Now, if I remember correctly, it was extremely expensive to get a supersonic flight on the Concorde, so this may produce (at first) a bit of false excitement. Boom Technology has a new supersonic airplane: XB-1. Here's the link. It has a grand total of 18617 parts. Please look into this.
