In routine flights, officers will normally be loaded in order of rank without regard for precedence, except that any VIP will be on- and off-loaded first; in alighting, officers will leave as they are seated from the exit forward--officers seated near the hatch will debark first, and so on to those who are seated farthest forward. In the event civilian dependents are being carried, or an enlisted man accompanied by dependents, they will be loaded after any VIP and before the officers, and leave in the same sequence. Aircraft carrying general or flag officers will usually be marked with a detachable metal plate carrying stars appropriate to the highest rank aboard, and will be greeted on arrival by the Air Force Base Commander, if the destination is an Air Force base. Other aircraft are usually met by the Airdrome Officer, who is appointed for one day only, and acts as the Base Commander's representative. Other personnel on active duty, seeking transportation on navigation or training missions, should realize that the flight is at the pilot's convenience. While the pilot will usually agree to any reasonable request, he can not deviate from his approved flight plan simply to accommodate a passenger. By the same token, passengers should be prompt, observe all pertinent safety regulations, and remain in the passengers compartment of the aircraft unless specifically invited to the flight deck or pilot's compartment. Under instrument conditions--so-called "blind" flying--continuous movement of the passengers of the aircraft makes unnecessary work for the pilot in maintaining balance, trim, and his assigned altitude. Passengers who are abnormally active while in the air are sometimes called--with exasperation--"waltzing mice." Since flights are somewhat dependent on weather, especially when carrying passengers, the decision of the pilot to fly or not to fly, or to alter his flight plan enroute will not be questioned by the passengers of whatever rank or service. Regulations governing the use of safety belts; wearing of parachutes; smoking during take-off, landing, fuel transfer, or in the vicinity of the aircraft on the ground are binding on all classes of passengers. When airplanes participate in the funeral of an aviator, it is customary to fly in a normal tactical formation, less one aircraft, to indicate the vacancy formerly occupied by the deceased. The flight should be so timed that it appears over the procession while the remains are being carried to the grave. Care should be exercised that the noise of the flight does not drown out the service at the edge of the grave. Other ceremonies, including Retreat and reviews, are the same for the Air Force as for the Army.
