ABSTRACT:
A giant column of air is employed to assist in the vertical take-off and landing of an aircraft. The column of air is forced through movable louvers which steer the aircraft on the air column. A pressure differential occurs on top of the air column so as to center an aircraft on the air column. In order to illuminate the air column, a salt spray is introduced into the column and a laser source resonates the crystals of the salt thereby causing energy to be radiated from the column which may be detected and displayed by an approaching aircraft.
