Lidar + Rogues + Duty - S3-E16
Factual error: MacGyver attaches a hose from a car gasoline filler port to the jet engine from a crashed plane. He uses a makeshift lever and the engine ignites. 1. A crashed jet engine has an astronomically low chance of working. 2. A jet engine runs on essentially refined kerosene with some additives. Automotive fuel would be useless. 3. The hose used to "provide fuel to the engine" is not siphoned to provide a usable flow of gasoline. 4. The braided wire hose is quite a long piece. It just happened to be lying there completely free of any holding clamps or terminations? How would just one piece of a long hose become free of the airplane? 5. The engine is not attached to anything, but the thrust of the lit engine does not move it one inch. 6. Even after being lit, it does not set fire to anything in spite of being in the middle of a lot of combustible material. (00:13:15)
Lidar + Rogues + Duty - S3-E16
Factual error: The pilot of the downed plane was flying a covert mission. If so, he should not have been wearing identifying patches, rank insignia, or an American flag. Especially ones that were not subdued. (00:18:00)
Lidar + Rogues + Duty - S3-E16
Factual error: Lieutenant Commander Reese is wearing flight wings on the left chest of his flight suit. They are not US Navy Naval Aviator wings. (00:21:35)
Seeds + Permafrost + Feather - S3-E17
Factual error: Bozer and for that matter I would assume all of the team went to a spycraft academy. A basic subject in any of such academies is surveillance, including proper techniques to follow and stake out someone. Bozer being so inept at tracking MacGyver's father is inconceivable given their training.
