The main benefits of such surface is its aesthetic, durability, and transportability. To improve air transportability and shipboard operations, all HH-60Gs have folding rotor blades. In 2005 the army relented on the vehicle's requirement for roll-off C-130 transportability. From their Fort Lewis base, they conducted Arctic, air transportability, amphibious, and maneuver training. Safety and design-specific capabilities, like transportability (fitting on an amphibious ship) were considered non-tradable. Attendees may be advised to package their produce both for good looks and for transportability. The first week of the course covered air transportability training, which included glider training. The front and rear suspension height can also be independently controlled for ship and transportability. Boston Confucianism also argues for the transportability of Confucianism to geographical locations beyond Asia proper.
