1. A ducted flow vehicle comprising:
- a fuselage having a longitudinal axis and supporting front and rear airflow ducts, each duct having a prime mover arranged to force surrounding air into said duct through an inlet at an upper end thereof thereby creating a lifting force directed substantially along a duct axis and wherein said ducts are formed with open areas along opposite sides of said fuselage configured for reducing sensitivity to side winds during flight of the vehicle.
