The pregnancy test Sarah has taken shows a plus sign for a positive result, but there is no line in the window under the C, which is the control result. This would normally indicate the test is not working properly, which as a physician she would know.
When Air Traffic Control calls Vincent Sandinsky's plane, the aircraft is addressed as "N727MG". Since the aircraft is flying into a US airport, the "N" should be omitted (because it simply means it is a US registered plane). Also, "MG" in proper radio terminology is "Mike Golf".
T-Bag states that elephants have the largest brain in the entire animal kingdom, when in fact it's the sperm whale that holds that record.
Part of the story takes place at the Indian Embassy in Miami. Embassies are always located in a nation's capital city. The Indian diplomatic mission in Miami, if there is one, would be called a Consulate.
When Air Traffic Control calls Vincent Sandinsky's plane, they mention a problem with the plane's "port side turbine." For that particular model aircraft, that engine is the "Number 1 engine", as engines are numbered going left to right. No pilot or controller would refer to it as simply the "port side engine".
The guards at the Indian Embassy/consulate are clearly wearing a Canadian Forces cap badge on their berets. The cap badge has a crown, and crossed swords, an eagle and an anchor representing The Army, The Royal Canadian Air Force and The Royal Canadian Navy, respectively. The badge is surrounded by red maple leaves.
When Christina is in the Indian embassy she asks the embassy correspondent about the ring he bought his wife from a "South African country". South Africa is a country. She should have said "Southern African country".
T-Bag addresses the Indian guard at the 'embassy' as Hadji. Hadgi means 'my pilgrim' and should only be used for a Muslim who has completed his pilgrimage. It is, however, possible, that this was a deliberate mistake that indicates that T-bag is not particularly educated and somewhat racist.
