I've been watching this Asteroid debate hang/don't hang. Having done commercial
suspended ceiling work a bit, might I offer some suggestions. I fully agree
with the ideas against hanging from the ceiling tile. I don't know how many
asteroids there will be (how many so far are there coming?) and how big they
will be but hanging them from the ceiling grid could prove disastorous. Those
hanging tabs don't hold a tremendous amount of weight for one. Secondly, if you
were to attach the asteroids to the grid it should be at a point where there is
support wire above. hanging them anywhere else may cause the collapse of the
grid in spot. Remember the grid only has to support light celing tile and
sometimes the grid may not be completely connected (enough movement could cause
a grid piece to sway out of poisition and therefore fall) they're supposed to be
locked into one another, but they don't always stay that way! Climbing up and
down ladders can be a bit tedious not to mention dangerous if the person isn't
use to doing it. Lastly the tile themselves are a concern. Many tile when
moved will shake loose little tiny bits of the surface and dust that has
collected, and makes quite a mess sometimes. Deffinately don't want bits of
fiberglass falling all over the place! It can be a pain to get the tile to fall
back in place to boot.
I think hanginmg them from the ceiling grid would look really cool, especial
over the moonbase, but it probably isn't worth the hassle, and may take way more
time then is available
