I found out tonight that the first transatlantic voice transmission was made between Arlington, Virginia (near the Pentagon) to the Eiffel Tower in 1915. Three radio towers stood there, and one was 600 feet tall. (The Eiffel Tower is over a thousand feet tall.) We tore our towers down in 1941 because they got in the way of our airplanes. This historical marker stands on South Courthouse Road (outside of a high security Department of Defense facility).
