Fortunately no harm was done but I suppose it's not inconceivable that it could have fallen through the trusses and onto the primary.
It's been discussed here and elsewhere and suggestions range from Dremelling a small hole, using some rubber packing or cable ties but noone seems to have come up with the definitive solution.
Edit:
Allan, after reading your last post more carefully, it seems like you are not having this problem with the same scope as mine (apart from the GoTo mount). Perhaps I just need to apply a bit more torque to the thumbscrew? (And a cable-tie just in case.)

Yes, I am not sure what the issue is.
I do not tighten it excessively, and only by hand.
I have had several SW collapsible Dobs and have friends with them as well, and I do not recall ever having the finder scope fall out, (even though it was always a concern due to the design, as discussed earlier).
It seems that some have a looser thread than others?
Maybe a bit of plumbers' tape?
