As regards the first part of the question, I would refer the hon. Member to the replies which I gave to him and to the hon. Member for Gower (Mr. D. Grenfell) on 17th May last. I would, however, take this opportunity of emphasising two points. Firstly, the display is essentially a collective culmination of the annual training programme of the Royal Air Force which is in any event necessary to the maintenance of efficiency. Secondly, the whole cost of providing the necessary enclosures and stands, and other incidental expenditure at Hendon is borne by non-public funds. No additional charge is therefore imposed on the Exchequer, and consequently no economy would result if the display were discontinued in its present form.
