Ke iho mai nei ko luna - S9-E13
Other mistake: A Five-0 member makes an atmosphere check of the Neptune 1 air. It shows 0.7% oxygen, 80% helium, and 16% nitrogen. A previous check had shown these were the only gases present. So what happened to the other 2.3% of the air? Helium and Nitrogen should have been proportionately higher so as to add up to 100%. (00:29:45)
