If you watch the Youtube of the clip below, you’ll notice that as the purple-sky effect begins there is a whoosh for each set of characters EXCEPT the ‘copter folks.
Bet gets a whoosh. Locke gets a whoosh. Sawyer and Juliet get a whoosh. Daniel and redshirts get a whoosh. Copter, no whoosh. Is there significance?
The only thing we can say for sure is that Ben was indeed transported into the future, and the copter folk were not. My theory is this: each person who got the woosh was transported through time. If the current theories about it being Daniel behind the camera in the Pierre Chang video, then Daniel would have been sent back in time. Could the order somehow imply the direction traveled?
