Deliberate mistake: This episode takes place in the country of Sudan on the continent of Africa. The Seals go to save some teachers at the American school. The school has concrete wheelchair ramps, asphalt paving, concrete curbs, metal railings. No school in Sudan has such architecture, especially asphalt pavement, its dirt, the asphalt would melt. There is also an empty real estate post used for advertisement in the ground. Majority have roofs made of metal, not briquettes. (00:16:00 - 00:17:45)
Ghosts of Christmas Future - S1-E4
Audio problem: One of the target's bodyguards is watching Jason and his team board a civilian plane, and he calls his boss and says "od jechal" which means he drove away. He should've said "odlecieli" which means they flew away. Also his Polish "od jechal" is heavily accented, spoken like he's speaking Arabic or something with a strong "H" accent. There's no way he's fluent in Polish. He also could've said "od frunal" which means flew away, but it's reserved for a bird or a small flying creature. (00:29:50)
Deliberate mistake: The Seal takes a shot with his suppressed pistol through a circular window in the hull of the ship at a hostage taker holding a hostage. When he fires through the glass it never breaks or shatters. Makes no sense how the bullet even passed through. In addition, windows in ships are really thick; it would've taken a few shots to get through and to neutralize the hostage taker. (00:33:30 - 00:34:30)
Ghosts of Christmas Future - S1-E4
Factual error: The Seals are in the briefing room and the speaker says their next target is "supplying the Taliban with the .50 cal armor piercing sniper rifles." Sniper rifles and rifles in and of themselves are not armor piercing, the only thing that is armor piercing is the type of ammunition that can be used in said rifles. Any high power rifle can have armor pricing ammunition made for it such as 7.62 Nato aka .308, .30-06, .338 Lapua Magnum, .50 BMG. A sniper rifle can use full metal jacket ammo too.

Other mistake: The team finds Ray's helmet which was shot off his head by a bullet. It was one of those 1 in a million shots that was lucky for him, and they do happen in real life. What I noticed earlier was the rest of the team is not donning helmets, they have plate carriers on though. It appeared Ray was the only one with a helmet. If anything he should've been the one without it since his HAHO jump went awry, and he could've lost gear. Doesn't make sense for one guy to don a helmet and the rest not. (00:30:35 - 00:31:00)
Answer: Yes. They would have to land 3-4 times for refuelling. The plane could fly with the wheels down, but the additional drag slows the plane and increases fuel consumption.
