1. An aerial load lifting system for transporting a load, comprising:

  • an envelope filled with a lighter-than-air gaseous substance;

    a structural shell for supporting the load, wherein the structural shell is shaped to allow the envelope to be slid horizontally into the structural shell such that the structural shell is surrounded at least in part by the structural shell; and

    a power train system including at least one engine supported by the structural shell and located above the envelope, and at least one rotor oriented in a substantially horizontal plane supported by the structural shell and located above the envelope, wherein the envelope provides a buoyant force essentially to offset the weight of the structural shell and the power train system, wherein the power train system provides a lifting force capable of lifting the load.
