Black Box UFO secrets

Reveals for the first time the cockpit and control tower audio recordings of pilot and astronaut confrontations and sightings of unidentified flying objects high in our skies. From a detailed account of one of the very the first reported pilot case, the Arnold case in 1947, to recent recordings over New England and Texas, to NASA recordings and video from 2005, this special features interviews with pilots, witness and experts, including UCLA's Joseph Nagy, actor Ed Asner, and pilot/UFO researcher Don Berliner.Go to the limits of human experience... and beyond. From the fringes of the galaxy to our own backyards, the UFO FILES searches for evidence of life beyond our world. Tracing the long, convoluted history of UFO encounters and research, this unique series opens new windows into the controversial field. The tape is always running, and when pilots encounter what they believe are UFOs, the black box aboard every aircraft captures the moment. For the first time, THE UFO FILES reveals actual cockpit and control tower recordings of these sightings. From a detailed account of the 1947 Arnold case, to recent recordings over New England and Texas, to NASA recordings and video from 2005, BLACK BOX UFO SECRETS features interviews with pilots, witness and experts, including UCLA's Joseph Nagy, actor Ed Asner, and pilot/UFO researcher Don Berliner. http://www.guba.com/watch/2000921008

Flight data recorders (FDRs) and cockpit voice recorders (CVRs), commonly known as black boxes, are devices used to investigate the cause of an aviation accident. Orange-painted and crash-proofed, FDRs and CVRs preserve vital information, such as the airplane’s speed and altitude, and conversations between the pilot, copilot, and air traffic controllers. When an aviation accident occurs, investigators from the National Transportation Safety Board (NTSB) often use the information collected by the FDR to create a computer animation of the accident. Combined with the conversations and noises recorded by the CVR, this animation often assists the NTSB in reconstructing the events that led to the accident. The Federal Aviation Administration (FAA) requires all commercial aircraft capable of carrying 10 passengers or more to have FDRs and CVRs on board. Most FDRs and CVRs record data on either metallic tape or computer chips.

FDRs record information such as the time, altitude, airspeed, heading (the direction in which the aircraft is traveling), and engine performance. FDRs also record the positions of the aircraft’s controls (such as flaps and stabilizers) and information that indicates whether the aircraft was pointed down or up, or rolling to the side. These various pieces of information are called parameters. FDRs typically record in a 25-hour loop. After 25 hours the oldest data is overwritten with new data. FDRs help investigators reconstruct the final moments before an accident. In the case of USAir Flight 427, which crashed in September 1994 killing all 132 people on board, the last minute of FDR data indicated that the aircraft began yawing (swiveling on its vertical axis) and rolling to the left as it approached the airport in Pittsburgh, Pennsylvania. This information contributed to the investigators’ conclusion that the cause of the accident was probably a disabling rudder malfunction that resulted in a loss of control. By order of the FAA, aircraft manufactured before October 1991 and capable of transporting 20 or more people must carry FDRs capable of recording a minimum of 17 different parameters by 2001. Similar aircraft manufactured after October 1991 must carry FDRs capable of recording 34 parameters by 2001. Beginning in 2000, newly manufactured aircraft must carry FDRs that record 57 parameters, and by 2002 they must carry FDRs that record 88 parameters. These new parameters will include information such as the status of the airplane’s cabin pressure and computer systems. The requirements are slightly different for aircraft capable of transporting less than 20 people.

CVRs typically monitor four channels: the pilot and copilot’s microphones, radio communications with the aircraft, and the cockpit area microphone (CAM, typically located on the overhead instrument panel). CVRs record on a 30-minute loop. After 30 minutes, the oldest data is overwritten with new data. The CVR provides information indicating how the pilots reacted to the circumstances that led to the accident. In the case of Flight 427, the CVR recording suggested that the rudder malfunction caught the flight crew by surprise. In other cases, the CVR may reveal that the flight crew was aware of the problem that led to the accident. An analysis of these recordings can help investigators determine whether the pilots reacted appropriately to the situation. CVR recordings can also help investigators determine if the pilots were misinformed by or misunderstood instructions from air traffic controllers, ignored crucial warnings, or were confused by weather conditions or other phenomena. The CAM records cockpit noise. Many aircraft instruments are equipped to give off sounds that serve as warnings to pilots. Examples include warning noises that the airplane is flying too low or is about to stall (lose its lift). These sounds add to investigators’ understanding of the scene aboard the aircraft. The NTSB often releases transcripts of CVR recordings. But the Congress of the United States does not allow the NTSB to release the actual recordings in deference to the families of the flight crew.
