A fixed wing type Vertical Take-Off and Landing (VTOL) aircraft retains a conventional seating arrangement and utilizes a single point VTOL lift source, in the form of a counter-rotating centrifugal compressor assembly having co-axially aligned upper and lower impellers. Air is fed to the upper impeller through a central intake, and to the lower impeller through either a VTOL mode intake or a flight mode intake. Air is exhausted from the impellers through a plurality of main air outlets. Each main air outlet is fitted with a thrust augmentation duct that can be pivoted downward for VTOL, or rearward for forward flight. A controller alternately closes the flight mode intake when the thrust augmentation ducts are in the downwardly pointing VTOL position, and closes the VTOL mode intakes when the thrust augmentation ducts are in the rearwardly pointing flight position.
