Thanks immensely to 'Researcher at Large' for providing me with scans of Norfolk Navy Yard photos and damage diagrams of HMS Illustrious after her bombing during Operation Excess.
I think it is fair to say that many of these pictures have not been printed or distributed before as researchers have picked over (and often not returned) copies in the British Admiralty Archive.
These pictures have been added (and more will be added) to the Operation Excess and Damage Overview pages.
