Factual error: The briefer on the oil platform mission says the platform is 12 stories, and 80 million square feet. Doing the math, that makes it half a mile per side if completely square. It is nowhere near that size as shown. The largest oil rig in the world - Berkut in Russia's Far East - has a combined deck area of only 342,000 square feet. (00:13:35)
Other mistake: In the hotel room shootout, bullets are being fired through the wall easily and tearing up the place as you'd expect. Frank then dives through the damaged wall and they shoot at each other with Frank behind a cupboard and Pilgrim behind an internal wall. But bullets empties into both of these bits of flimsy cover leave the men behind them miraculously unscathed.
Trigger Time - S1-E3
Continuity mistake: During the shoot-out near the end, the bullet holes in the pillars Frank and Kyle hide behind change and also disappear at various times. In one shot we see 2 holes when Kyle steps out to shoot, then when he ducks back when fired upon, the 2 holes are gone.
Continuity mistake: In season 4 of Prison Break, Mike Scofield's tombstone date of death shows 11-4-2005 but in this the date is 11-4-2010.
Other mistake: When Jessica calls Hondo to let him know about Deacon's wife, you see Hondo answer the phone normally. Right after she tells him what's up, you can see him holding the phone upside down, with the camera lens towards the bottom. (00:24:30)
Continuity mistake: Gandia dislocates his right hand thumb/wrist to free his right hand from the handcuff as shown from the back but the next shot shows a free left hand instead.
The Blessing of Many Fractures - S1-E8
Continuity mistake: During the fight with Zhou Cheng, Cheng does a forward flip and kicks Danny, making him stumble backwards. In the shot of Cheng lying on the ground, Danny is holding his stomach. In the shot immediately afterwards, he's holding his chest.
Borealis 301 - S1-E5
Continuity mistake: Near the end, Tom takes out the cipher key that was previously written on. But the cipher key used in the close up shots is different than the original. The words are spaced out and crossed out differently.
I Surrender - S1-E10
Continuity mistake: When Asha is in the hospital, her hair is pulled back and towards her right, away from the wound and a lot of her hair is next to her right shoulder. In the next shot of her, her hair has changed position.
Ashes, Ashes - S1-E6
Continuity mistake: Spoiler! At the end of the episode, after Elektra decapitates Alexandra, the blood pattern on her changes changes when she turns around and asks "any questions?" Most noticeably more blood on her forehead and two streaks down her chin that suddenly appear. (00:49:10)
Continuity mistake: Near the end of the episode when Nico is burning the photo of her father, she burns it at the top left corner in a close-up shot. Then in the following shot the photo is suddenly burning at the top right corner instead.
Factual error: The Navy Seals call in air support and provide a fire mission to given coordinates. The targets are engaged with rockets and gatling/chain guns. The UH-60 Black Hawk is shown leaving after the air strike. This UH-60 however only had mini-guns in the doors. The type of UH-60 needed for this action would be the UH-60 DAP, which is configured as a gunship and has no troop carrying capacity. The DAP can carry chain guns, mini-guns, missiles and or rockets. (00:03:00 - 00:03:23)
Other mistake: You don't have to look further than the name; the title of the series is "Knight's and Magic" instead of "Knights and Magic".
