Looking for two British pilots who towed across Atlantic 65 years ago

Any of our British friends know if either R G Seyes or F M Gobeil are
still around? 65 years ago in June, they piloted a Troop / Cargo
glider from Montreal Canada to Preswick Scotland as an experiment in
shipping these D-Day Silent Wings machines from the USA to UK.
Apparently the 6-7 hours ( per leg) of hand flying on tow over the
North Atlantic were determined to be too difficult and the flight was
not repeated.

If either of these heroic gentlemen are still with us - we should find
them and celebrate their flight this summer!
