Altimeter Black Table Clock
- 5 X 4 X 6 1/2 inches
- Cast, machined aluminum and brass
With its stout brass screws and industrial, rugged shape, the Altimeter clock is based on World War II aircraft instrumentation. The authentic dial holds part of a sub-dial that marked altitude per thousand feet. The main hands marked altitude per 10 and 100 feet. At sea level, on a desk or a table, this clock is a solid reminder of the marvel of flight.
In its extensive holdings of documents related to aeronautics, the National Archives keeps in trust records that begin with those of the National Advisory Committee that was formed in 1915 to study problems in flight and conduct research in aeronautics. NASA records are also held at the National Archives, as is the Wright brothers’ patent for their flying machine.
