Lummie

Corrected entry: In the movie, a news helicopter is flying somewhat close between the various Los Angeles CGI tornadoes that are tearing at the heart of the city. In real life, tornadoes are created by extreme turbulent vortex winds and heavy updrafts that affect areas two to six miles in diameter. One would not want to be flying a helicopter anywhere near an area that has just spawned a half a dozen tornadoes.

Correction: This shows more the stupidity of the people in the helicopter rather than a true mistake. Wanting good footage they probably decided to take the risk and keep going. Take the people standing around for example who were trying to film the event. Most of the people were taking the force of the tornadoes much too lightly.
