Sure, you can power the cap. That raises your cost significantly. And
would almost definitely be used to slow down the cap, to keep the cap
from
becoming a ballistic splat. *shudder* Bad thoughts of Kra'vak and
caps...
Terminal V is usually fast enough, it's the slowing down without hurting
that's the hard part.

Possibly... You're assuming mismatched aerodynamics. I will note, that
in
this atmosphere, a bowling ball and a feather, the bowling ball comes
down
faster. Yes, mismatched aerodynamics, but in the other direction than
yours. :)

First statement I won't agree with. Second sounds fine... But also
note
less fuel... Specifically I doubt it has enough fuel to accelerate and
de-accelerate... There's also the fact that at some point, you get a
very
ineffieciant way to ship people down... Lot of money, mass, and volume
per
pod for little to no advantage.

Yep, you can. No arguements. And if you put a jetpack on the back of
one,
they can catch someone without such. However, which will make it to the
earth, alive, first, the plane they jumped out of, the freefalling
skydiver, or the man with a jetpack?

Might I suggest reversing that... Clean the area first, then use the
base? You're more likely to penetrate the infected areas that way. Not
sure on this, however.
