I agree. Look at this from Ep 2. Timeline A - Plane crashed in water, all dead.
Timeline B - Plane crashed on island.
One is from when Miles goes up to talk with the ghost and when is when he comes down. Sorry to steal this thread from the other section, but this is kind of a different theory and this place usually generates more discussion from recently-aired episodes. Pictures seemed to have been posted twice
We know that the wreckage was found 2 months after the crash and we also know that Miles was listening to the radio which mentioned that the wreckage had just been found when he goes into the house.
Desmond pushed the fail safe key at the end of season 2 which, I believe, was 2 months or so after they had been on the island. If anyone can confirm this, then it is my belief that the button was pushed at some time while Miles was upstairs with the ghost. Him going back in time somehow affected the picture frames on the wall, which can logically be deduced from an almost endless array of scenarios.
