Other mistake: The human trafficker Sang Min covers his retreat from the warehouse firing wildly with a Micro Galil. In the time it takes for Steve to shout to the others if anybody is hurt, he somehow already ran all the way to his Mercedes deep up the alley and start it up so it can make a nice screeching noise and ram McGarrett. (00:34:50)
Other mistake: When Steve picks up the call from the Governor, his wristwatch points at about half past 10. The kidnapping, he then says getting to the location, happened one hour before, but during the opening his kid Evan whined that it was 6 am. Also to be noted, Steve in typical movie fashion is expositing the mission during the drive in the outskirts of town, as if he'd just have dragged his partner for miles without saying the first thing about the reason. (00:05:40)
Other mistake: The episode makes sure to mention the real places where the action happens. The fugitive escapes from Halawa Correctional Facility, and dumps the car at Kakaʻako Beach Park, which is about 25 minutes away. Danny and the others arrive at the location way before Steve, who was at the airport, which is roughly 15 mins away from the penitentiary (kinda odd that they'd happen to be even closer than him, but fine). They have then the footage to investigate, the guard to talk to, the game of hoops with the prisoners, go back to their precinct, but despite the huge headstart Ellers had, they catch the car that was abandoned "15 minutes earlier." Moreover, Chin calls Danny to tell him about the car only after he already investigated the location and interrogated the witness. It can't even be 15 minutes, because 15 minutes is when the fugitive bought the products from the market, and he still needed to dye his hair.
Other mistake: An important key to the first season's plot is the "dancing men" code on the postcard. We see the postcard several times leading up to Ep 1:13. It shows 3 lines of code containing 4, 4, then 3 characters. In this episode, however, Steve brings out his workings on a yellow legal pad to show the others. There are more characters on his pad than are on the postcard, and some of the characters (for example those with both arms on one side of their bodies) do not even appear in his workings. He claims to have used frequency analysis to work out the code. If one uses frequency analysis on the actual code we see on the postcard, the result can never be Hiro Noshimuri. (00:23:35)
Ua 'o'oloku ke anu I na mauna - S6-E3
Other mistake: The victim has been dead for six weeks, but when Steve and Lou enter his home, the printer is still printing bills. (00:19:35)
Ka makuahine a me ke keikikane - S7-E7
Other mistake: Halfway through the episode there's a drone view with the caption "RABAT MOROCCO". The clip is run backwards, with cars and people moving backwards, and smoke disappearing into a chimney.
Pua a'e la ka uwahi o ka moe - S9-E7
Other mistake: This episode shows a newspaper article about a Rolls Royce Phantom involved in an accident/murder. The article specifies it is a black car with a red interior. When the car is dug up, it has a black interior. (00:37:45)
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)
Other mistake: Lou Grover is searching an apartment when he comes across five silver-topped drug vials in a bag. He reaches in and takes four of them, and then declares he has found the drug dealer's inventory. Why did he leave one behind? (00:27:10)
Other mistake: Outside the convenience store, the robber somehow manages to rapidly shoot at Danny 9 times from a 6 shooter.
Hana Mao 'ole ka ua o Waianae - S9-E25
Other mistake: When McGarrett and Danny are on their way to the airport where Ian Wright is departing from, there's a shot of their black Camaro sliding through a corner. When they arrive at the airport it's not the same vehicle. (00:31:00 - 00:31:37)
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?
