Forty Years from Sand Island - S3-E17
Revealing mistake: When Higgins' wheelchair starts taking off and he cries "I say, MAGNUM!" you can see rise from the grass a thin line used to safely halt the chair when off camera. (00:28:05)
Two Birds of a Feather - S3-E19
Revealing mistake: In the shot when the plane tips over the tidal pool rocks, look at the tail of the plane to see the cables used to send the model plane crashing. (00:09:20)
Two Birds of a Feather - S3-E19
Continuity mistake: For the greater part of the air duel, the jet of the bad guys has one window, but in the landing and in other shots it has two windows. (00:45:40)
Two Birds of a Feather - S3-E19
Revealing mistake: When the airplane is shown from the front in flight (control tower saying "Squawk 0223 and ident"), the person standing in for Sato is wearing sunglasses, while Soon-Tek Oh is not. (00:42:50)
Two Birds of a Feather - S3-E19
Revealing mistake: The first shot of the bad guys asking to reroute from NY to Hawaii shows the plane with its license number mirrored. (00:42:15)
Two Birds of a Feather - S3-E19
Factual error: When Sam climbs on the plane to give chase to the baddies, the tail number is N64CE. When he takes off though, the control tower announces the clearance for "Sixty-four Charlie Lima." Should have been Charlie Echo. (00:41:35 - 00:42:30)
Two Birds of a Feather - S3-E19
Factual error: No matter how good of a pilot Samuel is, he's chasing a Learjet 24 plane with a WWII design P-51 Mustang (that he does not even know how to start, but of course fictional pilots can just 'wing it' and do amazingly). Assuming that speed is not a factor since the bad guy is not flying at top speed just yet (but still he has a projected arrival time of 6 hours, meaning he'd fly around 700 kmh), they do the chase at high altitude (42,000 feet are mentioned), with Samuel not wearing a mask or anything in a non-pressurized plane! He'd have passed out.
Two Birds of a Feather - S3-E19
Continuity mistake: The jet plane the bad guys are taking off in keeps changing registration number. Before Sam's heli lands, it's N94J, when Sam watches it take off it's 33BK, when it asks for authorization to change course it is N464CL. Its flag also goes from US to Mexico to US again. (00:40:40)
Two Birds of a Feather - S3-E19
Factual error: Sam crashes the plane running out of gas, but just barely. His boss and the client are mad at him, but he actually worked some miracle, since from Van Nuys to Honolulu there's a distance of over 2,200 nautical miles, and even considering additional fuel tanks, that is over 3 times the range of the Cessna 172 plane he was flying, also considering it had headwind throughout the voyage (it's even a plot point).
Two Birds of a Feather - S3-E19
Continuity mistake: After landing in Waco, Samuel hugs his mom. The propeller of the plane gets in frame, and its blades are angled with the right one towards the ground. Later Sam puts his slick moves on his ex wife, and when they pass by the plane the blades are horizontal. (00:25:30 - 00:31:10)
Two Birds of a Feather - S3-E19
Continuity mistake: When Sam's reluctant ex laughs after slapping him, she has her hand in front of her mouth when she is filmed from behind, not so in the previous view. (00:31:00)
Two Birds of a Feather - S3-E19
Revealing mistake: Sam arrives back home and he's greeted by his happy son and dog that run towards him...only, you can see at the bottom of the frame that the dog swerves to avoid him, to go to his handler, and couldn't care less about him. (00:22:50)
Two Birds of a Feather - S3-E19
Continuity mistake: The birthday boy is skygazing and talking with his dog. When he nags him for not listening, there's a cut to a close-up of Buckshot, and his floppy ear is suddenly atop his paw. (00:22:30)
Two Birds of a Feather - S3-E19
Revealing mistake: Higgins' spotlight gets turned off, not shattered by a bullet. (00:22:10)
Two Birds of a Feather - S3-E19
Continuity mistake: Sam Houston Hunter is ashore talking to Higgins about his Grandpa; his hair is messed up differently depending on the camera angle. (00:11:00)
Two Birds of a Feather - S3-E19
Continuity mistake: When the plane crash-lands in the tidal pool, it crashes with one wing and tumbles to the other side of the rocks, flopping on its belly. When Magnum dives in to the rescue, the plane has capsized and its tail is on Magnum's end of the rocks. (00:09:20)
Two Birds of a Feather - S3-E19
Continuity mistake: When Saito says to his assistant "I do not believe in accidents", the woman who was sponging his shoulder has her hands on the border of the tub. (00:14:55)
Two Birds of a Feather - S3-E19
Audio problem: When Mr. Sato on the phone asks "What is going to happen to my old bird", those last two words appear to be dubbed in and not match the lips. (00:14:25)
Two Birds of a Feather - S3-E19
Factual error: In his 'Nam flashback at the beginning, Magnum has (another) fun encounter with a large macaw. Green macaws (or any macaw for that matter) are not something he would have found in a Vietnam war mission, unless he inadvertently crossed the Pacific Ocean and ended up in South America. (00:02:00)
Visible crew/equipment: Higgins leaves for a trip. Once he closes the door, Tracy hunches over to ask Magnum if it still hurts, and in her big glasses you can see the reflection of set lights. (00:29:40)
