Visible crew/equipment: During the chase scene in the access tunnels under the dam, there are several shots where the camera is in front of Harrison Ford moving backwards, showing him as he runs from Tommy Lee Jones. You can see the tracks that the camera dolly is riding on.
Visible crew/equipment: After Sykes shoots the Transit Cop on the "L" Richard pulls the emergency brake, and in the following shot facing Richard as the train screeches in flashes of darkness, the reflection of a crew member quickly becomes visible on the glass window beside Richard. (01:47:45)
Visible crew/equipment: When Kimble is walking through town the morning after his escape from the bus, he passes by windows, and one shows a Steadicam camera man in the reflection.
Visible crew/equipment: When Kimble starts to move out from under the train, he looks up and we see smoke visible above. There is also a crew member looking down into the hole on the far right side of the opening. The person's head moves up at the end of the shot.
Visible crew/equipment: The camera filming the wide shot of the press conference with the US Marshals and Chicago PD blends in with the rest of the camera crews there doing the conference. It is blatantly visible behind everyone asking questions. The angle from this camera is used at least twice. You can identify it by its film magazine. Almost all news organizations in the 1990s used video tape as opposed to film, so a film camera used during a press conference would and does stick out like a sore thumb.
Answer: Kimble is watching as the doctor, Al, looks at the chest film and states "possible fractured sternum, he's stable," and we can see Kimble's bothered by that. Then Kimble is told to take the boy to observation room 2. When Kimble questions the boy and looks at the chest film, Kimble ignores what he was told, and instead heads directly for the surgical OR. In the elevator he draws a line over the incorrect essential diagnosis: "depress chest w/ poss fr" (possible fracture), and begins to write "Ao," then he scribbles a signature on the Patient of Dr line. The essential diagnosis Kimble writes is presumably an Aortic trauma, which is a life-threatening critical injury and requires immediate attention. So when Kimble brings the boy to the OR (instead of observation room 2) for the emergency medical procedure, he tells the doctor the boy was sent up from downstairs. The child is then taken to operating room 4, STAT, saving the child's life.
Its a pneumothorax, is air trapped between the lung and the ribcage and it's very common.
