Two people at the door of the 'plane, a man and a woman, he's holding her hand or arm, they are both wearing lifejackets. 
Here's the pilot blowing up the jacket he's going to give to the woman who didn't have one.
No tricks, both images are cropped from the same video still.
2:30 into last video you can see both pilot in white shirt to left and wing and man on it to right
Seems that IF that's Jacob Keys sitting on the wing, then the person swimming toward the aircraft could be one of the tourists?
On taking another hard look, he does appear to have a pony tail, I thought it was the collar of his shirt...the watch seems also to match the watch Jacob is wearing.
