I can't recommend both 'First Light- Geoffrey Wellum' and 'Warburton's War - Tony Spooner' enough. I was almost unable to put either book down, and ended up on Google researching both the subjects. Watching clips of Warburton's funeral, and the BBC's dramatisation of First Light.
I really hope I find out in advance when First Light is going to be repeated, so I can ensure it's recorded...
