The meteors are said to have hit at exactly 45 degrees north latitude. On the maps shown in the movie, one, Impact Site Alpha, hit in the Thunder Basin Grasslands of Wyoming, approximately 100 miles south of Wyoming's northern border. Wyoming's northern border runs along the 45th parallel. The impact in France occurred 20 miles south Lourdes. Lourdes is at 43 degrees north.
In a scene that begins at 1h 5mins of the film, Dr. Robert Pearlman (played by Dennis Lipscomb) asserts that angles of meteors' trajectories match those of Pioneer spacecraft, as presented in the "pixelated message that was sent on Pioneer 11". What he refers to is actually Arecibo message, sent on 16 November 1974 by Arecibo Observatory in Puerto Rico. This message has never been put on any spacecraft, instead it was sent by means of modulated radio waves. Hence, the shape Pearlman refers to is of Arecibo Observatory's antenna, and not of Pioneer spacecraft as presented in the film.
This probably got confused with Pioneer plaque - an aluminium plaque that really was put on Pioneer 10 an 11 spacecraft, which were launched into space respectively 2 and 1 year before Arecibo message. The plaque and message, while having similar goal of communicating with potential extraterrestial intelligence, look very different from each other.
During the TV program, the network goes to MASA's "Houston Space Center" where they talk to scientists who track asteroids. The facility in Houston is the Johnson Space Center which deals with manned spaceflights. It has nothing to do with tracking asteroids.
The goof item below may give away important plot points.
The garbled message recited by the French and the American survivors appears to say "As the Secretary General of the United Nations" over and over, yet Sander Vanocur immediately repeats the message as "147 member states".
