Factual error: The aircraft carrier towards the beginning is captioned as being the USS Enterprise (CVN-65), where Lt Rollins is stationed. It is obviously not the 'Big E', but a much smaller escort carrier or amphibious assault vessel. Notable differences are not only the sheer size difference, but also lacks the angled flight deck with the protruding catapult brakes, the second port side aircraft elevator and both the superstructure and bow shape are wrong.
Continuity mistake: At the beginning of the episode, when Grace Tilwell gets out of the Ford Taurus, she closes the driver's side car door. But once the shots change, the door is still open and she walks around the door towards the building.
Continuity mistake: Danny is taking to some Victoria's Secret models on the beach. They ask to see photos of his daughter. He is talking to them and he pulls out his cell phone from his pants pocket. Next shot, you see him reach for his pocket again and once again he pulls out his phone.
Continuity mistake: In first shot of Steve's dad's house ocean-,side, there is no crime scene tape, but two shots later as Steve enters from the back tape is shown in double rows across left side of back yard and across the length of the area under the upper deck. (00:10:25)
Continuity mistake: In the scene where McGarrett's dad's house is seen for the first time from ocean-side, deck on the top floor has furniture (wicker two-seat bench and two chairs under double windows with long table to the right) and the lower level has no furniture in grass to left of the ramp, and two large vases on either side of the ramp. Then two shots later (same scene) as Steve approaches under the crime scene tape, there is no furniture on the upper deck but now furniture to left of ramp and vases are missing. (00:10:25)
Continuity mistake: When Jerry is on the video call with Kono, he is wearing white makeup with red around his eyes, but when the shot shows him and the phlebotomist in the room, the makeup is gone.
Continuity mistake: When Jessie is being chased by Steve, she is wearing trainers (you can see the Nike logo on the side), but when she is in the interrogation room, she is wearing ankle boots.
Factual error: During the show, they flash back to November 1963 and have Don Ho in a nightclub performing "Tiny Bubbles." The problem is Don Ho didn't release that song until 1966.
A 'ohe ia e loa'a aku, he ulua kapapa no ka moana - S10-E21
Continuity mistake: When the Military Police take Lincoln into custody he's handcuffed, then both the left and right handcuffs switch direction while they're around his wrists, note the single and double bars, along with the chain links. Quite impossible. (00:31:40)
Visible crew/equipment: When showcasing the empty road as well as Danny's Camaro taking a sharp left for an action scene, there is a camera dead center in the road, and they drive right behind it. (00:28:59)
Ho'oma'ike - S5-E6
Continuity mistake: Mr. Weiss is in the hospital talking with Chin, Kono and Lou with bandages covering both ears that were supposedly chopped off by Sam Cole During the conversation we see the bandages change to above his right ear showing his ear is fine. Next the shot shows bandages are covering both ears, then the shot switches again with bandages above his right ear, then back to covering both ears. (00:31:22)
Revealing mistake: As you see Danny enter his office you can see Kamekona's reflection in the glass pane in the upper right hand corner of the screen above where Danny has a couple of pictures on a table, clearly waiting for his cue. A few seconds later is when you see Kamekona burst into Danny's office to discuss something with Danny. (00:02:13)
Ka makuahine a me ke keikikane - S7-E7
Continuity mistake: About to leave Doris' cell, Steve slings his backpack over his shoulder. 10 seconds later he does it again.
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.
Ka makuahine a me ke keikikane - S7-E7
Continuity mistake: Near the start Lynn goes to get more wine, carrying her wineglass. Switch to Steve sitting alone at the table - with Lynn's glass at her plate.
Continuity mistake: In the long bickering with Steve while they kinda talk with Sofia, Danny picks up the badge the Steve put on the table, put it down before the cut talking about bad relationship decisions, but in the next shot he's gesturing again with the badge. (00:23:10)
Continuity mistake: Steve and Danny sit at the diner's where they need to meet with the fugitive's girlfriend. As Danny gives Steve the speech about the "mammal to mammal" interactions he puts his toothpick in his mouth, but it vanishes in the front view, only to be plucked back at the beginning of the next shot. (00:22:35)
Chosen answer: They are Junior's SEAL buddies.
