A height finder is a ground based aircraft altitude measuring device.
Early height finder implementations were optical devices and later migrated to radar devices. Devices combining both optics and radar were deployed by the U.S. Military.
Famous quotes containing the word height:
“Much more frequent in Hollywood than the emergence of Cinderella is her sudden vanishing. At our party, even in those glowing days, the clock was always striking twelve for someone at the height of greatness; and there was never a prince to fetch her back to the happy scene.”
—Ben Hecht (1893–1964)
