HC Deb 07 November 1967 vol 753 c77W
36. Mr. Dalyell

asked the Minister of Technology what research he is doing into dangers to civil aircraft resulting from bird-strike by birds such as frigate birds with a seven-foot wing span, soaring above Indian Ocean atolls such as Aldabra.

Mr. Stonehouse

Investigations into the possible effects of bird strike on both civil and military aircraft have been undertaken at the Ministry's research and experimental establishments for some years. This work is continuing.
