It Seems Like A Interesting Design Interesting But I’m Not Sure If It’ll Ever Take Off. I’m Far

It seems like a interesting design interesting but I’m not sure if it’ll ever take off. I’m far from being an expert but the tri-engine design INCLUDING a liquid-fueled rocket engine sounds like a nightmare to maintain, especially since rockets engines aren’t usually considered to be safe enough for commercial transport.

Since turbojets are meant to be extendable (yeah, I’ve looked at the article), I’d like to remind anyone that complexity is usually prone to failures. Same goes for the rear fins (also change position in-fight). In my amateur opinion using turboramjets or internal turbojets would make more sense. Aaand... it wouldn’t probably look as depicted on the second picture.

And that is not including costs. No manned air-breathing airplane has ever reached speeds faster than mach 3.5, and the one that came close (Blackbird) was specially designed to handle these speeds. We have no experience at building near-hypersonic manned aircraft, especially meant for commercial human transport. Then, after each light rocket engines would have to be test-fired (just for safety) and probably replaced with a new one after every... lets be optimistic and say 30 flights.

Okay enough rambling... for now
