> "Boom" by Overture

It's literally just a model right now. Usually takes a bit longer than that to develop an aircraft, test parts, get manufacturing set up, get it approved/qualified by the FAA, then sell it. Not to mention how many companies and "idea" planes pop up already.

Unfortunately, without an engine or half-way working prototype, they haven't really even taken the first steps in development, at least not the challenging ones. If they already had made progress, I'd say they have a chance, but it's still way too early to have any hope.
