ABSTRACT:
A method comprises providing six helicopters. Each helicopter has a fuselage, a main rotor assembly extending out from the fuselage and rotatable about a main rotor axis, and four main rotor blades coupled to the main rotor assembly. The main rotor blades of each helicopter are moveable relative to the main rotor assembly between a deployed position and a stowed position. The deployed position is a position in which the four main rotor blades extend radially from the main rotor. The main rotor blades have a blade rotor diameter of at least forty seven feet when in the deployed position. The four main rotor blades are coupled to the main rotor assembly when in the stowed position. The method further comprises positioning the six helicopters relative to each other such that all six of the helicopters are simultaneously contained within a parallelepiped region having a height of less than fifteen feet, a width of less than twenty feet, and a length of less than one hundred forty five feet. The four main rotor blades of each of the six helicopters are in their stowed positions when the six helicopters are simultaneously contained within the parallelepiped region.
