Integrated engineering system that combines multiple drones and an electro-mechanical drone transportation system to achieve a new method of aviation transportation

An engineering system comprising:

• multiple drones;
• an electro-mechanical drone transportation system which is configured to transport said drones;
• said electro-mechanical drone transportation system including multiple carriers in the form of any combination of:
• a suspension cable carrier system, a magnetic levitation transportation system, and a rail transportation system including multiple carriers on wheels;
• said electro-mechanical drone transportation system configured to perform the steps of:
• in a middle of a flight journey said drones are configured to be transported by said carriers of the electro-mechanical drone transportation system, so that said drones are configured to increase a limit of aviation flight distance;
• said drones are configured to directly or indirectly communicate with said electro-mechanical drone transportation system via wireless communication, so that said drones are configured to attach to or to detach from the carriers of said electro-mechanical drone transportation system accordingly.
