Loved it! The first one is always the best. I kinda have to take some issues with the accuracy of it historically. After all, one of the radio operators did survive and told no tale of two madmen taking them prisoner and sending out a distress call before the real disaster.
In this, the inaugural episode, one fact was established that pretty much held true for the whole series.....that is when they were dealing with historical events, and not with the "Alien of the week" ......that nothing Doug or Tony could do would alter the final outcome of history. It would happen as history recorded it......perhaps even as a result of Tony and Doug being there.
