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.
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
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)
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)
