Thanks Jacko. William Roberts story is similar to my grandfather who transfered from the infantry to the RFC as a fitter/mechanic. After a second period of convalescing, this time after the Somme, he took an opportunity to swap the trenches for work on RE8s and enjoyed a number of ‘test’ flights. More to the point, he survived and, although he died in the late 60s, he and his colleagues left a rich legacy. I am deeply proud of him.
