The International Group for Historic Aircraft Recovery (TIGHAR) is a nonprofit organization located in Delaware, U.S.. Founded by Richard Gillespie in 1985, TIGHAR describes themselves as "a non-profit foundation dedicated to promoting responsible aviation archaeology and historic preservation." TIGHAR has long been involved with the search for Amelia Earhart, and advocates the theory that Earhart successfully landed on Gardner Island, now known as Nikumaroro.
Search for Amelia Earhart
Since 1988, TIGHAR has been testing the hypothesis that the missing 1937 flight of Amelia Earhart and her navigator Fred Noonan landed at Gardner Island. Archival research and multiple expeditions to the island have led TIGHAR to believe that the plane landed at the periphery of the atoll leaving Earhart and Noonan as castaways. TIGHAR notes that they still need conclusive evidence such as a piece of Earhart's Electra with a serial number or DNA evidence. In 2010 TIGHAR recovered bone fragments from Nikumaroro which they considered to be possibly human. Subsequent analysis of the fragments proved inconclusive. In 2012, analysis of a photograph taken in 1937 prompted TIGHAR to conduct an underwater search for Earhart’s plane. Though the search failed to yield any immediate results, TIGHAR later discovered a possible debris field through the examination of video taken during the expedition. In 2013 TIGHAR announced the discovery of a sonar anomaly at a depth of over 600 feet. After subsequent analysis revealed flaws in their sonar data TIGHAR indicated that the anomaly could be the dimensions of Earhart’s plane. In June 2013 Timothy Mellon sued TIGHAR alleging that they solicited a donation from him under false pretenses.
In addition to their Earhart related activities TIGHAR has been involved in a number of other archeological projects over the years. Since 2000 TIGHAR has occasionally offered aviation archaeology training through their field schools. In 1991 TIGHAR produced “The TIGHAR Guide to Aviation Historic Preservation Terminology” in an effort to standardize terminology within aviation archaeology.
