    at least some of them did. The Titanic incident spurred the adoption of wireless technology, which was already a Navy priority. In fact part of the history of Amateur Radio is that hams were using the same frequencies as naval vessels, which caused the Navy at first to attempt to put hams off the air, but then to talk the government into restricting them to frequencies roughly from the top of what is now the broadcast band on up. At the time that was considered worthless spectrum; hams soon discovered that those frequencies were capable of much more efficient and longer-distance communication than the medium-wave frequencies they had been kicked out of.

    However I don't doubt they used semaphore and other visual technologies in wartime. For one thing, if the other ships on your side could hear you on the radio, so could the enemy, at least in theory. Even if you were transmitting encoded messages, just the knowledge you were out there and perhaps a general direction would be a big advantage.

    You and I are going to spend our sunset years telling our children's children what it was once like in America when 25% of the population was batshit insane.
