Fuchs,

Maybe worth looking at Jon Custis project's website, albeit on a WW2 SAS navigator:http://mikesadlerproject.blogspot.co.uk/

The name is not familiar to me, but those who read the RFI might be interested in this short obituary:http://www.bagnallvillage.com/Biogra...lphBagnold.htm

Interesting to note it starts with:
leading authority on mechanics of sedimentary transport and eolian (wind effect) processes and instigator of the Long Range Desert Group
With contemporary application in the Sahel.
