Ne'e aku, ne'e mai ke one o Punahoa - S10-E8
Other mistake: When a helicopter encounters a problem and declares an emergency, the pilot declares a Mayday and says the craft is N-9128R. This is false. The registration on the helicopter is shown as N-437MY. (00:01:28)
Ne'e aku, ne'e mai ke one o Punahoa - S10-E8
Other mistake: Five-0 discover the camouflaged crash of a Cessna supposedly carrying 170 pounds of heroin (as mentioned previously) in the jungle. The heroin is indeed discovered inside the plane, but the heroin is still neatly stacked in the back seat, even though it does not seem to have been secured. Related, a DEA agent had mentioned that there was 100 million dollars worth of heroin being brought to Hawaii. 170 pounds has a street value (according to the DEA website) of $800,000 per 20 pounds. This would only be $6.8 million, not $100 million. (00:25:30)
Loa'a pono ka 'iole i ka punana. - S10-E13
Other mistake: Grover is going through the personal effects of a victim. He picks up a phone, attempts to open it and declares it locked. When it is put in the evidence bag, you can see it is open. (00:13:10)
Other mistake: The team, guns up, aimed, and ready, interrupt the meeting on the rooftop which has just ended in a shootout. Steve tells Cynthia to put the gun down or they'll have to put her down, and Junior menacingly cocks his rifle as if to emphasise the point. What, it wasn't already ready to fire? He's walked into a potential firefight with his weapon raised but it wasn't actually fireable yet?
Chosen answer: They are Junior's SEAL buddies.
