Ronald was too young to actually fight in World War 1 (although I believe he was with the RAF) but he was involved in the testing of early parachutes “Guardian Angels”.
Postscript: Many years later when members of the Parachute Regiment display team were at the Rowledge Fête, Ronald was introduced to them. This resulted in an invitation to dinner at their mess in Aldershot at which he was presented with a current Parachute Regiment tie, which he wore with great pride.
