This Is The Story Behind Why Pilots Say 'Roger That':

Ever since the first aeroplane was created, communication between the pilot and the ground staff has been a necessity. It is hard to imagine a pilot flying blind without any ground support and something that is not even remotely possible today. December 17th, 1903 marks the first successful flight by the Wright brothers and even they knew that communicating with the ground was an important aspect of the flight. Radios were not present at the time so they used visual aids like coloured paddles, signal flares, and even hand signs to communicate. The communication with the ground is something we don't give a second thought to these days but that is not how it has always been. The first air-to-ground radio communication used Morse code and since the pilots did not have the time to write full sentences while flying the plane, they used short signals for effective communication and to save time. In the time of these Morse code messages, one of the short signals was the letter "R", which was an abbreviation for "received". The pilots just transmitted R in order to let the ground units know that they received the message. Now we are so used to pilots saying "Roger That" that we don't give it a second thought. Where did these words come from and why do pilots all around the world say Roger That.
