There are way too many posters in this thread that hold on to some delusional process of seeing plane crashes in movies as science or fact.
There has been historic record of planes crashing in our vast oceans and disappearing for years at a time; and some never found.
I understand to those who want to hold on to some sort of hope. But the odds of anyone surviving a crash, based on the number of scenarios that are most likely, are absolutely astronomical--if not, impossible. To say that just because there is zero physical evidence, and that it equates to it never happening, is completely ludicrous.
Is there a remote chance of some other theory as to what had happened? Yes. But so far science and technology are proving us all wrong on these and points only and one or few more possibilities. So if you have some sort of other cockamamie theory as to what happened, try presenting it with some evidence or something that can truly discredit what we've all been following thus far. Because it's getting really old and stale after 7700 posts.
