Just had a thought about the 815 passenger list. We know they had the list but they never let it be known the names of those that died or were missing in the show. We know that it is possible to be transported into another time due to the flight 316 when Jack and friends went to 1977. This got me thinking that maybe it is possible that there were passengers on 815 that were transported even further into the past. Could Jacob have possibly have been a passenger on the plane? Just thought I would throw that out there.
