Substantial reduction in aircraft stowage space can be achieved by stacking aircraft using minimal or no folding of parts of the aircraft. This results in reduced complexity and reduced cost compared to other aircraft compact stowage schemes including for example fully folding an aircraft. Landing gear variable height, length, or orientation can be used to orient all or a portion of the aircraft for stowage. Alternately or in combination with such orientation by landing gear, other portions of the aircraft including tilting rotors and tilting nacelles can be oriented to achieve a geometric configuration conducive to compact stowage. In preferred embodiments, aircraft are moved relative to each other so that a portion of one aircraft is offset relative to a corresponding portion of the other. In especially preferred configurations, a portion of the first aircraft will overlap or lie on top of without touching a portion of the second aircraft.
