Can you post the image that makes you think that Jacob Key has dirty blond hair?
I think that is a guy not a gal. Jacob Key is next to his wife hanging onto the plane.
Look at the still photo of the video here:
Actually that link doesn’t help but put your finger over the wet bang strip on “the gal’s forehead” and you can see that it’s a guy or could be. Try it.
And I think that that is not a fat woman’s arm but rather the life vest around Jacob Key’s neck.
Inside the plane before the crash he is probably sitting next to his wife. Somebody else is sitting in front of Fuddy.
In the water his gray short sleeve shirt is pushed up over his shoulder or blocked by the life vest.
