Some people like to hop in a car to take a road trip across America, visiting as many landmarks as possible along the way. Since such a trek can take a while to complete, taking a flight across America might be a better option for some people. "Aerial America" takes viewers on such a flight, offering rare looks at some of the nation's best-loved landmarks from high in the sky. Cameras capture the history and pageantry of America as they zoom over busy cityscapes and quiet, rural lands. Many episodes focus on a specific state, showcasing highlights of the state's beauty, while others revolve around themes such as the best small towns and natural wonders found in the country.
Forensic Files
Eagle-eyed technical experts prove there is no such thing as a perfect crime as they assemble the pieces every criminal leaves behind. Dramatic crime re-creations and, sometimes, part of the investigations are a staple of the series. Some of the re-creations include alternate versions of the crimes, which are disproved by science. The show's episodes follow each case from the initial investigation until it reaches its legal resolution.
Air Disasters
Statistically, traveling by airplane is safer than driving and other forms of transportation, but when something goes wrong during a flight, it can be catastrophic with potentially hundreds of lives at stake. This series examines some of the world's worst air disasters, using official reports, transcripts and interviews with people involved to tell the stories of midair mishaps and discover what went wrong in each case. Episodes include a discussion of how the weather affects flights -- including stories of aviation disasters and near-misses -- and a New Year's Eve flight that fell from the sky into the Florida Everglades.
Air Crash Investigation
Catastrophic incidents in aviation history are meticulously re-enacted, providing insight into what went wrong and if the crashes and near-disasters could have been prevented; accounts from survivors combine with cockpit recordings and computer images to weave the gripping tales and expert testimony reveals the hows and whys behind the events, some of which have resulted in important changes to aviation safety and regulations.
