Anyone willing to do a scale estimate on the size of this thing? (to prove it's about 800m long?
When it crashes in the trailers, that saucer is enourmous.
It looks one deck thick at the rim, about ten in the centre hollow. Windows the same size as those on the Enterprise saucer rim and bridge. If the OP is right (and the scene where it drops put of warp backs this up), it's twice the size of the Enterprise - 1450 metres long.
