It is notable that the official Air Ministry file on the accident (File AIR 81/1660) is "closed", and therefore unavailable for public scrutiny, for 82 years, until 1 January 2030. This decision was taken by the National Archives in 2014 due to "Exemption 1: Personal information where the applicant is a 3rd party" and "Exemption 2: Information provided in confidence"
