An insect-plane which is really a flying motorcar is being prepared for her trials in a clearing in the New Forest - its inventor is Mr T A Dring ( aged 78 ) of Poulner in Hampshire - for 25 years he has studied the flight of hovering inects and is convinced that ordinary aeroplanes are built on wrong principles - his machine was two sets of rotor vanes motor driven and each projecting a stream of compressed air under the fuselage - if his theory is correct then expansion of the air streams will lift the insect plane - photo shows the insect plane being prepared for her first flight April 30th 1934
