China tried to pass off clips of the movie Top Gun as footage of their air force.
Recently, China Central Television (a state-owned television station) aired footage of air force training exercises during a news program. The clips featured an American plane being shot down. Internet commenters were quick to point out that the plane was the same plane that Tom Cruise flies in Top Gun. In fact the footage appears to be identical from a scene in that movie.
You can compare the frames from the broadcast with the frames from the corresponding Top Gun scene at Gizmodo or on this Wall Street Journal video. (The original footage has been taken off of the CCTV website).
