I am not in agreement with most theories espoused about the crash but...
Even though Puentes video was edited it tells us something important. What are the odds that all the passengers could be so calm after the plane's ditching? All are shown serenely exiting the plane like their exit was rehearsed or maybe known about before hand. One or two being calm --- believable, but all nine?
Now, now cal you are NOT supposed to ask such question, you may hurt somebody’s feeling. Now you go over to the “silent” corner for awhile, and ask for forgiveness!!!
Was the Miracle on the Hudson rehearsed because it sure seemed like the passengers exited the plane in a very calm manner.
But than who really knows what they were feeling inside, except for themselves of course.
