HC Deb 27 January 1972 vol 829 cc503-4W
61. Sir J. Langford-Holt

asked the Minister of State for Defence what action is taken on the 10 per cent. of all reports of unidentified flying objects for which there is no explanation; and how long these reports are kept.

Mr. Lambton

9.3 per cent. of the reports received at the Ministry of Defence from 1959 to 1970 remain unexplained because insufficient information was given. No further action is taken, but records of unidentified flying object reports received since 1962 are kept indefinitely.
