Fly Socks
Description: "I have received your last transmission satisfactorily, radio check is LOUD AND CLEAR." "ROGER" may be used to mean "yes" with regard to confirming a command; however, in Air Traffic Control phraseology, it does not signify that a clearance has been given. The term originates from the practice of telegraphers sending an "R" to stand for "received" after successfully getting a message. This was extended into the spoken radio realm during World War II, with the "R" changed to the phonetic alphabet equivalent word "Roger". The modern NATO phonetic alphabet uses the word "Romeo" for "R" instead of "Roger", and "Romeo" is sometimes used for the same purpose as "Roger", mainly in Australian maritime operations.
Description: Flight is the process by which an object moves through an atmosphere (or beyond it, as in the case of spaceflight) without contact with the surface. This can be achieved by generating aerodynamic lift associated with propulsive thrust, aerostatically using buoyancy, or by ballistic movement. Many things can fly, from natural aviators such as birds, bats, and insects, to human inventions like aircraft, including airplanes, helicopters, balloons, and rockets which may carry spacecraft.
