Speed kills. Blast kills. How much energy is delivered to the target?
That question is all that matters.

Yup, if you drop a common 30-50lb crowbar from orbit
its going to inflict a world of hurt on whatever it hits
notwithstanding its simply an inert piece of metal.

a crowbar probably would not hit the ground (ever seen a long thin
iron meteor?)

Meteors are not man-made either. It's the same concept as an armor
piercing tank round. Long and thin to concentrate the density in a
small frontal cross section. And it would not really have a curved end
like a crowbar. I hope.

are we still talking about dropping from orbit?


Vince
I think so...

Project Thor I think was the name proposed. There are severe problems
with targetting however. Looking through the plasma generated by
reentry is a major problem and at hypersonic speeds last minute
manoeveuring is not a real option.
