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).
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.
Chosen answer: It is part of the ritual for la Santa Muerte. It is a sign of humility and sacrifice.
