THE FIRST OF A SERIES: On his first flight with his new Cambridge sailplane, the Duke of Grafton (right) obtained his "C" certificate. This machine, designed and built by Zander and Weyl, is the first of a small series and has already proved itself with soaring flights of more than an hour's duration.

At the other end of the string: Mr. E. J. Furlong’s Cambridge II zooms skyward the rather emotioning fashion typical of the winch-launching.

The Cambridge University Club’s Cambridge I in tow behind an Air Publicity Avro 504, flown by Mrs. Crossley. This machine, with an Airwork Gipsy-Cadet, made some scores of tows during the week, operating from Mr. Alan Butler’s private aerodrome near-by.
