Chemical Mary (No. 143) - S8-E7
Factual error: French (and other nations) ATC rely on ground-based radar to track aircraft, not GPS from the cockpit of an aircraft. Meanwhile, whilst the aircraft that had been tampered with had compromised systems, the TCAS radar on the plane flying in the other direction would have alerted its pilots to take avoiding action.
Ogden Greeley (No. 40) - S8-E8
Factual error: During the scene in a London bar, the emergency exit sign is red (and not green as required by UK law). The signs adjacent to the toilets are unlike the ones regularly seen in the UK, as are the US style light switches and a 110v power outlet in the ladies' toilets.
Helen Maghi (No. 172) - S9-E16
Factual error: Harold tells Raymond he'll repay the bail money, but given he's pleading guilty and fully intends to go along with required court appearances, etc, the bail money paid will be refunded - it's not like Raymond is out-of-pocket.
Factual error: The airline boarding pass from Melbourne, Australia to Zurich shows the code MLB, instead of the correct code MEL. The code MLB is for Melbourne Orlando International Airport in Florida. (00:58:40)
Answer: The man Red killed, Sam Scott, was Lizzie's adoptive father, not her biological one.
