Theme Dinner: Regional Sky Transit: Landing & Takeoff System on Latching Drone Cars and Ground Taxiing & Passenger Assist System

Using electric-latching-platform cars for runway operations enables extremely-short takeoff or landing (ESTOL) capability for long-range electric fixed-wing aircraft between low-noise highly-localized RST skyparks. This concept means short runways, less landing gear weight, and future integration into last-mile connections with street-or-air transport pods. This technology could be significantly advantageous in the...
