Word on the street is that the Oxygen bottle went up into the cabin near the attendant seat, hit the fire extinguisher and the portable oxygen bottle there (both are missing as well) where the valve of the big bottle was knocked off, which got propelled onto the door handle, which itself turned but the shaft (bolt) of the handle sheared, the big bottle itself with its valve now missing then went further up into the ceiling and, with the 2 smaller bottles (fire extinguisher and portable oxygen bottle), went back down and out through the hole into the open.......
