The RAF High Speed Flight will be attending with two Supermarine S.7b flown by Henry Waghorn and John Boothman.
The ailing R.J. Mitchell has refined the S.7 further this year with some aerodynamic improvements but mainly hopes are pinned on the RR 'R' III with its ethanol/ petrol mixture and now producing nearly 3,000hp.

Gloster will also enter an aircraft. Henry Folland and his team have designed an aircraft remarkably similar to the S.7 but with a smaller wing and much lighter weight. It is also powered by an 'R' III engine thanks to the donation of the engine by Rolls-Royce who have built eight 'R' III engines this year. The Gloster VII will be flown by an unknown flyer, Alex Henshaw.
