The only raeson they may not put it back is because the person being challenged is the one who started the thread. At the time it was pulled, there were no "personal" attacks going on. It sounded like one professional challenging statements made by the other.

Sometimes the "rules" on CC get a bit fuzzy. I try to stay within guidelines and don't have my posts deleted very often.

Hopefully, when there is more information on the recent Apollo/Mark Conroy visits on the Voyager and Mariner, a new thread will be started. The information posted, from those who really could see what was going on, were great!
