>>10763446>Because it's so massive that it would be impossible to build a launch pad that can both hold the thing and survive the launch.
I am willing to accept that, but the first part is clearly untrue, larger towers are held up by their foundation "pads" all over the world. When I looked at the engine size (>>10763455
) I am more willing to believe that building a pad that would not get wrecked would be difficult.
Dropping it in slat water is counter-intuitive times the the square root of negative infinity over zero, but that is not in and of itself evidence of anything.
Still, I'd look into fresh water launch locations, just because slat water hates things like electrical systems or metal parts so fucking much.
At the end of the day, though, it was a harebrained idea that might well have worked, but which nobody really wanted. Which is too bad, it would have been amazing had it worked.
(Not sure we'd have yet built an engine that big that worked reliably, but hey...)
