I was attached to 4AEF to hold during my flying training, and spent many hours with Rufus in the air and on the ground. Once, he introduced me to low level battle formation over Dartmoor as we transited to Plymouth to fly cadets, and on another occasion to night formation on a delayed return to Exeter from Yeovilton. Never be allowed, these days! His tales from his time as Wg Cdr Spry were highly entertaining. My condolences to you and your family.
