Very cool and will be interesting to see how it goes for them.
It originally was to have an F1 engine in that role but it fell through (can't recall why off the top of my head, there's been a ton of articles about this thing over the past few years so it should be easy to find if you're interested).
No, it's substantially different and talk about missing the forest for the tree. You missed the forest, ran right into the tree, and then somehow missed the bear taking a shit on your statement because that's about what it is worth.
That speed difference is kinda exactly the reason why this vehicle is different from a jet while on the ground.
Can you people just stop with the stupid shitass analogies? It's literally a purpose built vehicle for trying to go 1000mph on a salt flat. A jet "flying" on the ground |) and a car "driving" in the sky |) both have to deal with aerodynamics, gravity, friction, and more or less the same things, just at varying levels.
