Pua a'e la ka uwahi o ka moe - S9-E7
Continuity mistake: McGarett starts to work on a case file on his kitchen table. It is evening. His wrist watch says 9:13. The scene dissolves several times as he yawns and finally falls asleep. The wrist watch now says 9:10. (00:09:45)
Pua a'e la ka uwahi o ka moe - S9-E7
Continuity mistake: Right at the beginning of the show McGarrett and Dano are driving. The left windshield wiper is missing, then it is there in the next shot. Then both wipers are missing missing a few seconds later. (00:00:50)
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)
