"used as a directional device to help pilots navigate back to friendly airfields. As technology developed planes were able to use telegraph systems to send messages in Morse code. Telegraphs used a plunger to complete an electric circuit. When the circuit was completed it sent out a signal as a dot or a dash. By depressing the plunger devise in a rhythmic pattern a telegraph operator could spell out words, with each dot- dash sequence representing a corresponding letter in a word. Using this technology planes were able to call in accurate artillery fire and act as forward observers. In"

The letters ""S"" (), ""C"" (), and ""R"" () all consist of three dots, but the timing is different in each case.

He drew dots and dashes in the sand similar to the shapes used in Morse code. After pulling them downward with his fingers, producing thin lines resulting from the dots and thick lines from the dashes, he came up with the concept of a two-dimensional, linear Morse code,"
