Ok so in the epsiode dead is dead we see the scene where ilana had found, presuming their guns that were smuggled onto the plane somehow. Now if you notice the boats seem similar to the ones that were in the season 5 premiere. I think that when the island was skipping through time one of the flashes took the islanders to the point in the future when the Oceanic 6 plane had already crashed. and the people shooting and chasing sawyer and juliet and the rest were ilana and her people after they found the boats on the second island and made there way to the beach camp. That was why the camp was still there, ravaged threw, and the boats were docked on there beach. There is a missing piece that might be far fetched because the 06'ers were on that plane to and yes the flash removed them and put them in 1977 but if this was the case and it was ilana in the boat chase then that means when the flash in the plane occurd i! t messed with time and 3 years some how passed in dharmaville with sayer and juliet before jack and them arrived. Maybe it kinda paused their life when until sawyer and juliet, and the rest of them became part of the initiative and then transported the 6ers excluding sun to 1977 and unpaused them in a way, thats why both groups realize it has been 3 years. because if this wasn't the case it would been 3 for dharma and 6 for the 06ers.
I know it seems weird but who else would be going to beach camp with guns and boats, its not the old others that flame arrowed them becasue that took place in the past when the camp wasn't there. the boat chase needed to take place in the future because the camp was there and it looked like someone has went through everything. the only other explanation is that it is the future others that locke was leading once ben left, but that doesn't seem right because when locke flashed through time none of those peolpe did.
