A folklorist and senior lecturer in journalism at Sheffield Hallam University, Dr David Clarke advised The National Archives on the Ministry of Defence UFO files released from 2008 to 2013. On the first release, 1.7 million downloads came in the first few days. He also revisited older cases. With Andy Roberts, he argued in 2013 that the Solway Firth Spaceman was Annie Templeton, whose dress had been overexposed to white. He called the Cosford Incident a classic case of misinterpretation. In 2022 he tracked down the Calvine photographer, and he leans towards a secret aircraft as the explanation.
