Natty, if you read my post, then you must have noticed it started with your statement, "Most of them were never heard from again."
I was not reacting to the means of their departure from Roswell, but the fact that you said "Most of them were never heard from again," i.e., what happened to them AFTER they were kidnapped.
I was simply suggesting that AFTER they were kidnapped, their final disposition may have been explained quite innocently as "assimilation" rather than something nefarious as suggested by "most of them were never heard from again."
Pardon me if I did not state my thoughts clearly. Does this clear it up, Natty?
