Assignee: KITTY HAWK CORPORATION
Field: Transport (Mechanical engineering)
Classification: CPC B | IPC B

Claim 0:
1. A system, comprising:
a plurality of propellers that generate vertical thrust at least some of the time;
an attachment sub-system that detachably couples to a vertical connector, wherein a plurality of vertically-stacked multicopters detachably couple to the vertical connector in order to transport a load at a bottom end of the vertical connector; and
an opening in a vehicle frame that: (1) receives the vertical connector prior to the attachment sub-system detachably coupling to the vertical connector and (2) holds the vertical connector while the attachment sub-system is detachably coupled to the vertical connector; wherein:
the system is included in a second-from-top multicopter in the plurality of vertically-stacked multicopters;
the attachment sub-system:
detaches from the vertical connector; and
after moving into a topmost position associated with the vertical connector, detachably couples to the vertical connector; and

the system further includes a flight controller that: after the attachment sub-system detaches from the vertical connector, generates one or more control signals for the plurality of propellers associated with moving to the topmost position.
