Thirteen pages, and it's been explained 5 times just in this thread both O2 bottles contained O2 on the Doria Dive - and he still can't get it that the O2 bottle was filled with air AFTER the Doria dive and BEFORE the trip to Florida. Sigh... So ridiculous.
No, that is wrong.
The O2 bottle could not have been filled with Air after the Doria dive because it had and always had O2.
Jesus Fing Christ....no kidding! There were TWO O2 bottles on the doria dive! He used ONE! Fillies that used one with AIR and put it with the other bottle that had O2 still in it. He never changed the markings on the non O 2 containing cylinder and MONTHS later he grabbed the bottle filled with O2 instead of the one filled with AIR! He REFUSED to analyze the cylinder and died from his own idiocracy...Maybe you have a point...foul play should have been assumed by the police. Charles Darwin predicted the outcome of this dive over a century ago...he must have had something to do with it.
