Factual error: When the militants are preparing to burn down the building, a contractor twice reports that they are spreading diesel around. Diesel does not burn under normal circumstances and will only combust under high temperature/pressure. (00:51:50 - 00:52:30)
Suggested correction: "Diesel does not burn under normal circumstances" FALSE. Just like it's Brethren Fuels, Jet - A and Kerosene, Diesel Fuel burns at the touch of a flame. Please don't conflate combustion with ignition.
Diesel will not ignite if you throw a flame into it. The flashpoint of diesel is approximately 140° Fahrenheit (60 Celsius). This means in most ambient temperatures it will not ignite. The fuel would not have ignited in the conditions show in the film.
Factual error: Sean Smith is shown playing "Call of Duty: Advanced Warfare" on an Xbox. That game was released on November 4th, 2014, over two years after the date of the attack (September 11-12, 2012).
Suggested correction: It was Modern Warfare being shown on the TV. Advance warfare uses exo suits and can't be missed.
