Factual error: When the planes crash over Albuquerque, when the bear is falling towards Walt's house, there is a quick shot of Albuquerque suburbia and mountains. Two major streets are visible, the one on the right is Eubank Blvd and the one in the lower left is Wyoming Blvd, both which run north and south through the city. This means the shot is facing north. There are no mountains immediately north of Albuquerque as shown. The closest mountain range, the Sandia Mountains, are on the east side and wouldn't be in that shot. The closest mountain range in the north are the Jemez Mountains, which are 40 miles away. They would barely be visible in that shot (they would look like blue hills in the distance).
Other mistake: When the bear is falling through the sky after the plane crash, it is shown through its point of view. When it starts falling, a shot of northern Albuquerque is shown but when the bear turns over, suddenly it is facing the east. Eubank Blvd is a major north and south street, is seen in the shot of the north. In the latter shot, Candelaria Rd, which is a east and west street is visible. When the bear spun over, it should be showing Eubank Blvd going south.
Continuity mistake: When Skylar is packing, one shot of her has one color clothes that she's putting in the suitcase and the next shot of her has different color clothes. This happens two or three times. (00:39:00)
Continuity mistake: In the scene where Walt and his wife are talking at the breakfast table the milk carton is facing a certain way. Five seconds later it has completely turned the other direction. The wife is holding a baby, and no sound is heard to indicate that she moved the milk carton in any way. (00:10:17 - 00:10:22)
Revealing mistake: When Mike is putting on the second glove to clear up the evidence in the bedroom, Jane's eye can be seen twitching briefly, even though she is supposed to be dead. (00:06:20)
Visible crew/equipment: Near the beginning, there is a shot of the one-eyed toy. The camera is riding on the cart with it. You can see the shadow of the camera in the lower left frame.
Continuity mistake: Sitting outside a crack house looking for Jesse, Mike and Walt are talking in Mike's car. When Mike says he could just be mugged or shot, the camera is behind their heads. Walt turns his head towards Mike while he's saying this. When the camera angle changes, suddenly Walt is looking out of the passenger window again.
Factual error: On the radar screen, a flight, SAA332 is seen. SAA is the icao code for South African Airways, which did not serve any city near Albuquerque in 2009.
