The slow, tight circling of the plane crash site from the naval pilot's point of view would be impossible in his light aircraft. It obviously was filmed from a helicopter.
Night scenes in the Everglades were filmed in daylight hours and underexposed to make it appear dark. However, this technique leaves the scenery, including the sky and background, much brighter than night. The fact is, at night in the Everglades, without light, one would be able to see nothing and, therefore, would not be able to move about without difficulty. One would constantly be stumbling and tripping over roots and logs, and stepping into holes, mud, and water. There would be no clear or easy walking as shown.
(at around 2 mins) As Ramon is running away, he runs straight at the taxi, making no effort to avoid it There is a slight but perceptible cut, then he (or his stunt double) is hit, lands on the car's hood, and rolls off to the side. In addition, there is a continuity error in this scene as in the long shot he lands on the street with his arms outstretched above his head, but in the closeup of his body he arms are down.
When the dancer is in the cafe, the music of the piano part stops, but the piano player keeps moving his hands quickly on the keyboard as if he is still playing.
Mountains are visible in the background at the Jacksonville, Florida airport. There are no mountains anywhere near Jacksonville.
The government did not know what airplane the smugglers were in, yet there was a bulletin describing it so the airport worker recognized it.
The Navy pilot radios they are going to crash in the Everglades. After the crash, he states that two men and a woman are going down river on the raft. Then he notes that "four others are heading into the jungles where they'll be bait for crocodiles or water moccasins." While there are some American crocodiles in the Everglades, alligators are much more likely to be the danger.
