Dropping a Mountain
- What if a huge mountain—Denali, say—had the bottom inch of its base disappear?
What would happen from the impact of the mountain falling 1 inch? What about 1 foot?

and then the whole thing were allowed to drop to the earth? — John-Clark Levin

Orbital Speed
- What if a spacecraft slowed down on re-entry to just a few miles per hour using rocket
boosters like the Mars-sky-crane? Would it negate the need for a heat shield? — Brian
Is it possible for a spacecraft to control its reentry in such a way that it avoids the atmospheric compression
and thus would not require the expensive (and relatively fragile) heat shield on the outside? — Christopher Mallow
Could a (small) rocket (with payload) be lifted to a high point in the atmosphere where
it would only need a small rocket to get to escape velocity?— Kenny Van de Maele

NO
He's an Apathetic Retiree. He doesn't have enough mustard to catch-up that much.
But then, neither do any of us.

My goodness me (to the relativistic baseball)!
There was a "Slow down" campaign in Sweden a number of years ago, and I remember one poster saying (but in Swedish) "It is the velocity that kills you".
Isn't that true.

Velocity is what starts the ball rolling for other events to take place that makes the Big mess that does you in.

It's not the velocity, it's the abrupt
reduction in velocity that gets ya. [We need a SPLAT! smiley.]

But with the "relavistic" baseball (which never makes it to you), there isn't any abrupt reduction in velocity, it's the nuclear conditions that it generates that gets ya. [We also need a little mushroom cloud smiley]
