Trivia

 * To achieve the exterior of the Helicarrier, the filmmakers shot on a runway at the Albuquerque International Sunport.
 * It is almost similar to the Ultimate version of the S.H.I.E.L.D. Helicarrier that is used. The only difference is the Ultimate version almost looks like a Destroyer-class battleship while the movie version looks like a Aircraft carrier-class ship.
 * Also, if you notice that the main engines and some parts of the ship resembles that of the Daedalus-class ships from Stargate: SG-1.
