[0000] Improved aircraft, which may be configured as unmanned drones or piloted aircraft, having improved fail-operational performance. The aircraft includes a twin fan arrangement and innovative motor, propeller, driver and/or power source redundancies configured to provide fail-operational functioning in the event of failure of one or more of these aircraft components. In various optional features, the aircraft may be configured for vertical takeoff and landing. The disclosed embodiments provide an aircraft that is safer and more reliable than current multi-propeller drones, while operably more versatile in cargo delivery.
