§ Mr. Biffenasked the Minister of Aviation what representations he has now had on the effect of supersonic flights on domestic and farm animals; what replies he has given; and if he will make a statement.
§ Mr. MartenMy right hon. Friend has received representations from the National Fanners Union, the Farmers Union of Wales and from individual farmers. In reply, it has been pointed out that 90 per cent. of supersonic test flights during the past 12 months were carried out over the sea but that in order to reduce the risk to pilots and aircraft, and for other technical reasons, a small number of such flights must be made over land. The number of claims in respect of damage to livestock has been very small in proportion to the number of overland flights. Further study into the effects of sonic booms on animals is being made in co-operation with the Ministry of Agriculture, Fisheries and Food.
