Crashing Ships, Mind Flashes, and Time Skips by TST

We all know what happened in the season 4 finale: BLOOP. The island disappears.

In the first scene of The Incident, we see Jacob and MIB having their famous conversation while a ship, probably the Black Rock, is sailing toward the island:
JACOB: I take it you're here 'cause of the ship.
ENEMY: I am. How did they find the Island?
JACOB: You'll have to ask 'em when they get here.
ENEMY: I don't have to ask. You brought them here. Still trying to prove me wrong, aren't you?
JACOB: You are wrong.
ENEMY: Am I? They come. They fight. They destroy. They corrupt. It always ends the same.
JACOB: It only ends once. Anything that happens before that is just progress.
ETC.

After waiting what seemed like forever, we find out what happened to the island: it went skipping through time. We also know that Sawyer and Juliet and Miles saw the statue in the last time skip. That was probably the same moment that MIB and Jacob were talking.

We assume that course correction takes place to make sure whatever happened happened. Desmond stopped Charlie from dying a few times, but Charlie dies anyway.

What if Jacob stopped the ship from crashing in 1845. He can keep stopping it from crashing, but it would eventually crash anyway.

During that final time skip, the Black Rock gets caught in the bubble around the island and crashes in 1974. That would explain why Horace has never heard of it.

While the ship lands in 1974, not all of the people on the ship do. Some of them are sent to 2007.

That would also explain how the ship has been there at least since 1988 when Rousseau and her team got to the island.

We know that one of the time skips lands the losties in 2007, when Richard takes the bullet out of Locke's leg. It would make sense that flight 316 got caught in that time skip. Sun, Ben, and Co. stayed in 2007 while Jack, Kate, and Hurley got caught in the time skip. They don't remember what happened after the turbulence and the flash of light. They just woke up in the water in 1977.

I think that Jack and co. were sent back to 1974 just like Sawyer and co. in the time flash.

What they don't know and one thing I think will be shown in season 6 is that Jack, Kate, and Hurley woke up in a mind flash like Desmond did on the freighter. He did not remember anything from the time he was in the military to the time he was on the freighter. They do not remember anything from 1974-1977.

I don't know what happened in that time, but they probably found the Others and worked out a plan with them. Same thing with Sayid. That is why Sayid and Jack feel they have a purpose.

That is my theory. One thing that I know some of the people reading this will not like is that Richard Alpert was not part of the Black Rock. I really have no clue as to who he is, but I'm sure it will be explained in season 6. Anyway, let me know what you think!!
