HC Deb 10 February 1955 vol 536 c251W
98. Mr. Wigg

asked the Minister of Supply the date on which it was decided that the wings and ailerons of the Vickers Valiant must be redesigned; and what percentage of these aircraft, at present in use by the Royal Air Force, have been so modified.

Sir E. Boyle

The Valiant wings have not been redesigned. In December, 1954, it was decided to modify the ailerons to overcome undue vibration in high speed flight. This modification is being incorporated in all Valiants being delivered to the Royal Air Force.
