I should be interested to know what steps you have taken so far to further your knowledge of the operation, other than reading Vulcan 607; which is hardly source material. Freedman would be a much better starting point. Have you searched in the National Archives for any snippets others may have missed?
It would also be useful if you could explain what use you intend for any information you might glean and your previous involvement with similar programmes.
The main participants told their stories years ago and there really is little or nothing left to tell.
