The 825th lecture to be read before the Royal Aeronautical Society, “ Planning ami Production Methods Used in the Construction of the de Havilland Comet,” by H. Povey, A.F.R.Ae.S., was given at the Institution of Civil Engineers, Great George Street, London, S.W.I, on Thursday 12th April 1951. Major G. P. Bulman, the President of the Society, presided.

Opening the meeting the President said they met that evening in the shadow of a grevious loss sustained by aviation throughout the world, and by the Society, in the unexpected death of Mr. W. G. A. Perring on 8th April through heart failure. The shock to those of them who worked with him and knew him well was still so deep that one could not try to pay an adequate tribute to his great services.
