Package delivery system

A system for delivering packages from a warehouse to end destinations, the system comprising:

• a fleet of self-propelled long-range transports;
• and
• a fleet of containers, each configured to be loaded at the warehouse with packages destined for end destinations;
• and
• a fleet of self-propelled short-range transports;
• wherein each long-range transport is configured to be loaded with at least four of the loaded containers and transport the at least four of the loaded containers from the warehouse to one or more intermediate destinations;
• and
• wherein, upon arrival of one of the loaded long-range transports at one of the one or more intermediate destinations, at least one of the loaded containers is separated from the loaded long-range transport, whereupon the separated container is loaded on one of the short-range transports, which one of the short range transports travels to and delivers packages to end destinations for the packages in the separated container proximate to the one of the one or more intermediate destinations;
• and
• wherein, after delivery of at least some of the packages loaded thereon at the warehouse, the separated container is transferred from the short-range transport back to the long-range transport and returned to the warehouse to be loaded with more packages.
