Not only do I think we should be able to buy Concordes, take a look at what I got for flight sim!

In 1970, United Airlines agreed to purchase 4 supersonic jets (Which by the picture above is named as a Concorde*. Yes, that did make no sense.), then backed out of it.
*If I had said that it was a Concorde instead of a supersonic jet (there are about 2 that I know of), then that might be plagerism.
