Audio problem: When trying to get Waddell on the radio, Galentine says he can't reach them. Camera changes and he's stopped talking but his mouth continues to move. (01:21:40)
Factual error: After the second Black Hawk helicopter (Super 6-4) gets shot down, all of the crew members aside from the pilot appear to have been killed in the crash. In reality, all of the men survived the crash. They were later killed by the Somali mob, except for pilot Mike Durant who was taken prisoner.
Suggested correction: Black Hawk Down is frequently regarded by many, including real participants of the battle, as a dramatization of what actually happened. Therefore some details will not match up to real events. This is simply one of those instances.
Suggested correction: Mike Durant in his book "In the Company of Heroes" states that this did not happen.
Visible crew/equipment: Just after Pilla is killed we see Aidid walking with his MP5. In his sunglasses the camera is reflected as clear as day. (00:48:20)
Suggested correction: That wasn't Aidid, and the person you mention didn't have an MP5.
Visible crew/equipment: When Grimes takes out the technical, he dives to the ground when an RPG explodes near him. As he hits the ground, a camera covered by a blue and grey blanket can be seen to his left.
Revealing mistake: When Josh Hartnett is talking to his friend's body near the end after his friend was killed in action, he touches his friend's chest. You can see the actor jump because he wasn't expecting Josh to touch him or wasn't prepared for it, his eyes even twitch and almost open.
Visible crew/equipment: The rocket launcher hits the transport truck and blows the Ranger out with his legs gone. When the convoy begins to stop you will see the Humvee with the gunner and beside him is the cameraman.
Other mistake: When several of the Rangers are carrying Blackburn's litter up to the target building and they cross an intersection, you can spot an empty, stationary Black Hawk helicopter at roof level further down that alley/street as one of the Rangers fires at the Somalis. This was after all the Black Hawks had gone into their holding pattern. (00:48:15)
Continuity mistake: Blackburn falls from the chopper and Eversman looks out the side with his goggles on. Camera shows him from outside the chopper and he doesn't have his goggles on. (00:40:20)
Continuity mistake: Grimes asks Wad why he isn't shooting back. Look in the background and you can see Eversman call Galentine over and say something to him. We then see a clip of the fire fight followed by Eversman calling Galentine over again. (00:45:20)
Continuity mistake: When Eversman explains about the situation, the guy in the background with the little book about the Somalians has the book up by his mouth in some shots and down by his side in others. (00:18:20)
Visible crew/equipment: Hoot cuts in front of Blackburn at the base. As Blackburn says about there being a line, a camera is reflected in Hoot's sun glasses. (00:14:20)
Continuity mistake: We see Mr Otto's convoy in the desert. In the shot of Mr Otto when the Black Hawk comes down into shot, there are 3 people in the side door. When we see the driver of the truck, there are 4 people in the side door area. Camera goes back to Mr Otto and now there are 3 people again. (00:06:05)
Revealing mistake: While running at the very end, there is a close-up shot where a Ranger lifts his rifle to fire. We see it recoil against his shoulder, and we hear several shots, but he doesn't pull the trigger. His finger lies flat against the gun. (02:04:05)
Continuity mistake: At the start, Mr Otto states he is just a businessman while his cigar is in his hand held away from his face. Camera changes and his cigar is in his mouth. (00:07:10)
Revealing mistake: When Mr Otto's convoy is seen at the start all 3 trucks are kicking up a dust trail. However is one of the long shots, the first truck is not kicking up a dust trail and the bit of dust that was up in the air has disappeared. (00:05:50)
Continuity mistake: Grimes gets handed a death letter and he holds it up. Camera changes and his arm and the letter are not in sight, which they should be at that angle. (00:29:00)
Continuity mistake: When Blackburn is reporting for duty, he asks what it's like. Grimes then puts his hands out, palm down. Camera changes and his fists are now clenched with no time to clench them. (00:11:30)
Other mistake: During Mike Durant's capture the helicopter circling overhead that broadcasts "Mike Durant we won't leave you behind!" is the voice of Tom Sizemore who plays Col. McKnight - it even says so in close captioning." Col. McKnight was in the streets of Mogadishu engaged in battle at that time. (01:44:45)
Factual error: In the movie the first Black Hawk helicopter (Super 6-1) gets shot down and just so happens to crash in a large four-way intersection. In the actual battle, Super 6-1 crashed in a narrow alleyway. (00:49:45)
