The crew did file reports with MI9 as is shown on this link, search for Irvine on the page:
http://www.conscript-heroes.com/MI9-03.html
The crew is listed in order following William J Irvine, who was the pilot. Note: The "existence" of a report does not mean that they escaped or evaded, only that they were interviewed.
These reports are not on-line, but are in the National Archives at Kew, WO 208 (3298 to 3327) and could be ordered.
Here is the search result for William J Irvine.
