Mimiki Ke Kai, Ahuwale Ka Papa Leho - S9-E3
Continuity mistake: At the start, Meaghan Rath winds down her window and leans out to yell at the guy behind her. Leans back in, we cut to a shot outside the car and her window is instantly up.
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)
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
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)
Pua a'e la ka uwahi o ka moe - S9-E7
Factual error: A 1932 haulage receipt is shown on screen. It says Hawaii, HI. There was no such abbreviation used for Hawaii until June 1963. The territory was spelled out in full. In June 1963 it was HAW, and then changed to HI in October 1963 with the advent of ZIP codes. (00:38:50)
Pua a'e la ka uwahi o ka moe - S9-E7
Factual error: The episode refers repeatedly to a brand new 1941 Rolls Royce Phantom II. The Phantom II was discontinued in 1936. It should have been a Phantom III.
Mai ka po mai ka 'oia'i'o - S9-E9
Continuity mistake: When Jerry visits the comic store, the girl behind the counter brings him a new batch of comics. In that frame, the register's screen in front of her has a new Microsoft Edge web opened. The camera then refocuses on Jerry and Grover. A few seconds later, the camera refocuses on the girl behind the counter showing the register's screen has something else opened. (00:25:05)
Pio ke kukui, po'ele ka hale - S9-E10
Continuity mistake: Before the gunfight, Joe tells Steve not to wait too long to find someone. There's a shot of the boards over the window beside him, and they're fully intact. Seconds later, when he says "no visual", well before the gunfire actually starts, they're suddenly riddled with bullet holes.
Hala I Ke Ala O'i'ole Mai - S9-E11
Continuity mistake: The McGarrett team is seen loading a US Coast Guard C-130H. Shortly thereafter, a takeoff shot shows a C-130, but it is not a Coast Guard aircraft. (00:08:10 - 00:11:00)
Hala I Ke Ala O'i'ole Mai - S9-E11
Character mistake: Ensign Rollins is shown in her office in a flashback. Her boss comes up and addresses her as "Lieutenant Rollins". An Ensign (O-1) is not a Lieutenant (O-2 or O-3). (00:32:40)
Ke iho mai nei ko luna - S9-E13
Factual error: Three divers arrive at Neptune 1 submarine station where they test the atmosphere at 3% oxygen, 80% helium, 17% nitrogen. Breathing that much helium would make their voices quite high pitched. But their speech is normal. (00:14:30)
Ke iho mai nei ko luna - S9-E13
Factual error: A Neptune 1 dweller is suffering from a panic attack. One of the Five-O members asks if they have any oxygen. Using pure oxygen at that depth could be fatal. At 14 atmospheres of pressure - the pressure of Neptune 1 - pure oxygen would definitely cause oxygen toxicity. Oxygen toxicity is a concern for scuba divers who dive beyond recreational depth limits, use gas blends such as enriched air nitrox, or use 100% oxygen as a decompression gas. Pulmonary oxygen toxicity causes a burning sensation in the trachea, coughing, shortness of breath, and eventually lung failure. (00:14:45)
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)
Ke iho mai nei ko luna - S9-E13
Continuity mistake: McGarett is going to free dive to Neptune 1 to take some scuba tanks to the crew below. We see him get in the water, and there is one tank ready to be passed to him. In the next shot he is being given the tanks, only now there are two. (00:37:10)
Ke iho mai nei ko luna - S9-E13
Factual error: Full aluminum scuba tanks are 1.5 pounds negatively buoyant when full of breathing air. Two of them would be 3 pounds negative. Yet McGarrett is using them to propel him down to 127 meters as if they were very heavy weights. (00:37:25)
Ikiiki i ka la o Keawalua - S9-E14
Factual error: A bomb maker is seen soldering a printed circuit board. He has a soldering iron in his left hand, and a voltmeter probe in his right. There is no reason to have a voltmeter probe on the board. First of all you would need a ground probe as well, not a soldering iron. Second, when you are soldering you need to feed the soldering iron with a soldering wire, which he is not doing. (00:20:15)
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)
Factual error: A defibrillator is needed immediately. Adam runs to a storage closet and rummages around for a while, and finally finds a defibrillator deep under other things. This medical clinic is a public place. No one would ever bury an automated external defibrillator (AED) under other items in a storage room. AEDs would be visible and accessible for just such emergencies, as instructed on the devices themselves. (00:35:35)
Ai no i ka 'ape he mane'o no ko ka nuku. - S9-E18
Continuity mistake: Jerry is briefing the team. He says that HPD processed "the van" and found... This is the first mention that HPD even found a van. They were looking with keys found on the victim to see if nearby vehicles would fit them, but there was no prior mention that they had found any vehicle at all. (00:08:50)
Other mistake: Outside the convenience store, the robber somehow manages to rapidly shoot at Danny 9 times from a 6 shooter.
