Happy Landings! is the universal toast among aviators.
The significance of that toast is deeply rooted in the peculiar characteristics of the airplane and its uses. For, unnatural as it may seem to the uninitiated, it is not the departure from terra firma that presents the greatest difficulties in the training of the new aviator, or the daily work of the seasoned pilot, or the design of the vehicle that either is given to fly. The take-off of any airplane is relatively simple. It is the return to the natural element, the landing of an airplane, which is fraught with the greatest hazards, presents the greatest complexities in acquiring mastery of its accomplishment, and furnishes the stumbling block which many otherwise promising designs of airplanes fail to surmount.
