It's cool, and no small achievement, but I want to see 400mph.....

If pressed, I'd rather see 300 on a sit-on, but both would be cool....

But what I'd REALLY like to see, is the sound barrier broke on 2 wheels. I really don't care what the configuration is.... Back when Thrust II did it, that was ultimate! (I think, I might have my facts wrong).

That is just plain awesome! Breaking the sound barrier is sweet. If this race takes place, that would be even cooler. And that looks like a hybrid design, no? A true rocket engine hybridized with a trubine engine..
