You can read more about Wally’s time in Bomber Command by visiting ‘raf-bombercommanad.co.uk’

Completing a full tour of 30 operations in one aircraft must be unusual, if not unique!

Interesting (and tragic) reading, including the first account I’ve ever read of any bomber crew dying of oxygen starvation.

P.S. You may wish to edit your link as it doesn’t work spelt that way.
