Ninety years on

I am holding a book, its foxed pages commemorate the records of service of the staff of a bank in "The Great War 1914-1918". It is open at the entry Albert Norman Ryley. The record is short.

... in April 1918, being 1 month under 18, he joined the Royal Air Force as a Cadet. He had become a Flight Cadet when demobilised in March 1919.

He was my father.
