I have concluded that the clip shown on the film footage from time frames 10:52:52:01 to 10:52:52:10 are of my father PO Hugh William Reilley being interviewed by the Intelligence Officer.
In this post, I have included a picture taken of him just before he departed from Canada in 1939 which shows a strong likeness and note that Hugh was one of the few Pilots to ware a white Flying Suite to help in his identification.
The still shot below is copied from the Clip, the full version of which can be
viewed by following the YouTube link given below.
This picture was extracted by Mr. John Tate, the organizer of Gravesend Airport Facebook page,
for which I am most grateful.
