During 1908 he designed a glider in collaboration with Lieutenant W. B. Pirie (1888-1960). The glider tested 17 August 1909 from the north side of Portsdown Hill near Portsmouth. Launched using rails like the Wright Brothers, the event featured on the front page of Flight magazine. The aircraft was a staggered wing bi-plane flown by two pilots simultaneously using a system common to airships; one having control of the rudder and wing warping, the other control of the elevator. The use of staggered planes apparently preceded that of the Goupy. Both officers were attached to the submarine depot at Haslar.
