Factual error: An An-12, the aircraft the main character uses to fly all over the world, has a maximum range of about 3,500 miles. Hardly enough to fly from the US to South Korea or from South Korea to Israel. The An-12 also miraculously transforms into a C-130 in a couple of filler scenes. And why is this ex-Soviet aircraft marked in USAF markings, assigned to McGuire AFB?
Factual error: Gerry and Thierry use Iridium 9555 satellite telephones to communicate with each other. These telephones require a clear view of the satellites in order to operate, however both are able to communicate even when a clear view of the sky is impossible, such as inside an aircraft or in the bowels of a warship.
Factual error: Atarot Airport in Jerusalem has been closed since 2000. Even when open, it was a tiny regional airport only designed only for eight propeller passenger planes, not the major international airport depicted.
Factual error: When Gerry is in Camp Humphreys, the leader of the group there tells him to make sure Maverick keeps the nose of the plane pointed towards the sun. However, since they're going to Jerusalem, and it's night time, they would likely be headed West, therefore not towards the sun but rather in the opposite direction. (00:48:40)
Factual error: When we are at the Welsh WHO facility we get an exterior shot during the night where we hear crickets chirping. This is a classic US film-making error. There are no crickets in Wales or any part of the UK. What you would hear at night is silence. Maybe owls.
