Re: Bomb weight

I have a question about the weight of the various asteroids or
what-have-you being used for the bombarment. I think I recall seeing a
figure about 90 tons? Was this just an example?  I ask because while
pouring thru my SJ stuff for a current project I ran across a rule for
bombing in the Complete Spacefarer's Guide. It says that a ship can
launch a rock of up to half its tonnage.but to do so it has to be towed
into the stronghold's atmosphere envelope
(granted you are bombing a planet not a asteroid base) and remain
stationary  for a full turn while it aims.  The rule also allows for
bombing runs.

Another thought when using the above rule in a planet's atmosphere how
do you remain stationary above your target without anchoring yourself to
the target? Considering that spelljammers tend to drift with the wind
while in a planetary atmosphere.  If it was a calm day your court wizard
could always pop out and whistle up a gust of wind or  like-spell and
the threat goes drifting away.

Just some thoughts,
