Area 51 and the U-2 test strip
1955
Lincoln County, Nevada

A dry lakebed picked as a test strip for the U-2 spy plane, and later the A-12 and the first stealth aircraft. The government would not admit the base existed until 2013, which is a large part of why it collects the folklore it does, high-altitude aircraft nobody was allowed to explain.
That was 1 of the hidden places.
