Not necessarily. Your giant balloon will shrink as it falls into denser
atmosphere. IF the ration of weight of gas inside balloon vs weight of
air being displaced by balloon changes, then bouyancy changes.


Yes, but likely not the way YOU want it to.


Note that the ship
they're talking about using to 'catch' it is intended to catch free
falling objects (like fairings).

Then if it falls on a mattress/net, what are the odds that it remain in
usable state?


Pretty good if they can actually catch it.


If they catch it in the air by the balloon, can the heliocopter land
the hanging stage II onto some sort of receptable on ground that will
provide proper support so it isn't dropped on engine bell with
expectation it remain standing without damage?


If they catch it by using guys Roman riding on teams of Pegasi, they
can just fly it back to land. Any other moot speculation you'd care
to engage in? The idea is for it to hit the net. Did you even bother
to read the ****ing article that was linked?


They already do a commanded deorbit burn to drop the stages in the
Pacific so they're not cluttering up orbital space.

Thanks. wasn't aware of that.


It was in the linked article. So either you didn't read it or your
famous memory is once again in play.
