The concorde....maybe Project Mach
Yes, it looks like a good ol' Projet MACH, which unfortunately has been "crapped" because its website does not exist anymore. Last time I checked it out for updates about 15 days ago or so, and the site was already down, and ever since that, it is still down, so I have deleted it from my favorite websites and decided to stop paying a visit to hem for updates. But a good bet would be that Concorde still exists "somewhere" on the web, try looking at Google . . .
