The Silver Spitfire
I have just read The Silver Spitfire, by Tom Neil. He wrote it at the age of 92!
Neil was a 23 year old RAF Squadron Leader who was posted to the 100th Fighter Wing of the USAF. While flying P-51 operations in France he discovered and commandeered (for himself) an abandoned Spitfire.
Great insight into how the USAF fighter wings operated and how comparatively easy it was, in a war zone, to retain a Spitfire as a personal chariot.
