[3] He was killed after crashing his Lancaster in thick fog near Kelstern following an operation to bomb Berlin (the infamous Black Thursday).

[3] Holford was inspired to join the RAF when his uncle Air Com D’Arcy Greig competed in the 1929 Schneider Trophy in a Napier-engined Supermarine S5.

He flew six missions with Flight Lieutenant Percy Pickard, who portrayed the fictional Squadron Leader Dickson, in the 1941 propaganda film, Target for Tonight.

For his actions that day, Holford was awarded the Distinguished Service Order (DSO) and promoted to squadron leader aged just 21.

Seeking to land at RAF Grimsby, Holford's Lancaster flew into the ground near Kelstern with only the wireless operator and tail gunner surviving.
