The Invention of Precision Navigational Instruments for Air and
Sea Navigation
![]()
In May of 1919, eight years before Lindbergh’s famous solo flight,
three small planes set out from Newfoundland headed for London in an attempt to
make the first trans-Atlantic flight. Only one of them made it. Twenty-five
hundred feet below on board a station tracking ship, a young navigator, Lt.
Cdr. Philip Van Horn Weems, U.S. Navy, gazed up and thought there must be a
safer and simpler way than using a small armada of ships as beacons for the
flight.
