Meet The Team

The Trustees of the RAF Pathfinders Archive, in order of their joining the Archive, are: Jennie Mack Gray, Kristine Johnston, John Clifford and Sean Feast. Below – in their own words – is a brief outline of their backgrounds and interests. At the foot of the page, you can find Pete Tresadern, our first Associate Researcher, whose main speciality is 35 Squadron.


Jennie Mack Gray – Chairperson

JMG at Bourn, 1996
JMG – First visit to the old station RAF Bourn, 1996

I have been researching the Second World War, the RAF, and the aftermath of the war since 1995.  The photograph above is of my first visit in 1996 to see what was left of RAF Station Bourn where my father Peter Mack, a wireless operator in 97 Squadron, was stationed in late 1943. The man I am talking to is Jim Hansford, a local resident who knew much about the old wartime station.

In 2016 I completed my doctorate at the University of Exeter, my thesis being on the British and their dead servicemen in North-West Europe after the Second World War. This included the intensive work which the RAF undertook to trace the many thousands of aircrew missing in Europe. The renowned historian Professor Richard Overy was my doctoral supervisor.

In a previous incarnation I was Founder and Managing Editor of the Gothic Society, writing, editing and designing publications such as The GothUdolpho, and many others too numerous to mention.

My main books on the history of the Second World War are:

Fire By Night, The Story of One Pathfinder Crew and Black Thursday, 16th/17th December 1943

‘Major Cotterell and Arnhem: A War Crime and a Mystery’

‘This is WAR! The Diaries and Journalism of Anthony Cotterell, 1940-1944’

They were published under the name of Jennie Gray. I have changed my pen name to Jennie Mack Gray due to the very unfortunate coincidence that my name, with exactly the same spelling, is also that of someone convicted in an appalling child murder case.


Kris Johnston – Founding Trustee & Legal Advisor

Kris started her legal career in private practice in London, before continuing it in local government.

She was on the management board of two East Midlands local authorities, responsible for a wide portfolio of services. She specialised in governance issues and co-authored a Code of Practice on Planning which was used nationally.

Kris was officer Chairman of a number of inter-authority bodies (regionally and nationally), including the Sparsely Populated Councils Group. She was Chairman of the East Midlands Community Legal Service Partnership.

Her interest in history ranges from the Pathfinders to the medieval period, including its art and architecture.

Pete Tresadern – Associate Researcher

Pete Tresadern started his RAF research in 2013, initially focusing on the loss of a particular aircraft and then expanding it to cover the wartime activities of 35 Squadron, a key Pathfinder squadron.

He has created a 1,500+ page website which contains information on all of 35 Squadron’s WWII operations, aircraft and personnel and he has also built up an extensive archive of original source documents which he has utilised to help over 250 families learn more about their relatives who served with the squadron.

He also provides information and support to various museums and memorial rooms which house 35 Squadron related exhibits, and raises funds for new memorials to commemorate squadron losses or for ongoing maintenance of existing ones.

His aim is to preserve the history of No. 35 Squadron for future generations and to ensure that all who served with the squadron are always remembered.

His work has enabled him to acquire background information on a wide range of subjects covering the time an airman joined the RAFVR through to the time of his resettlement, so he may be able to put this knowledge to use and point you in the right direction on non-35 Squadron related enquiries.
