Giddings was conscripted into the Royal Air Force Volunteer Reserve in 1940. On 1 November 1941, he became a Sergeant in the RAFVR. He completed his pilot training in the United States of America. Upon returning to Britain, he joined No. 122 Squadron RAF, based at RAF Turnhouse, and flew Spitfires. With the squadron he flew patrols over the Firth of Forth. He moved with them when they were reposted to RAF Hornchurch in the south of England. He then flew sorties over northern France. In July 1942, Giddings flew from the aircraft carrierHMS Eagle, situated in the Mediterranean, to Malta. In August he joined No. 246 Squadron RAF and provided air support for the convoys involved in Operation Pedestal. On 1 October 1942, he was regraded to the rank of Pilot Officer on probation. During that month he flew as many as four sorties a day, and shot down at least two enemy aircraft, including an Italian Macchi C.202, and damaged numerous others. He was involved in the defence of the island from the Axis powers until November 1942, when he was injured during an accident. He was taking off when a truck appeared on the runway in front of him. He crashed into it at high speed and broke a wrist and an arm. He then returned to England to recuperate. On 1 November 1943 he was promoted to Flight Lieutenant, and on 1 September 1945 this was made permanent. He later was given seniority from 1 September 1945. During the summer of 1944, he was made a flight commander in No. 118 Squadron RAF. With them he flew the Spitfire IX. With the squadron he took part in the Battle of Arnhem, and shared the destruction of a Messerschmitt Bf 109. In February 1945, Giddings was awarded the Distinguished Flying Cross. The citation published in the London Gazette on 9 February 1945, reading: In April 1945, he became the commanding officer of No. 129 Squadron RAF.
Giddings was an independent panel inspector with the Department of Environment between 1979 and 1991. During this time he presided over many inquiries concerning motorway expansion. He presided over the year-long inquiry in May 1982 concerning the extension of the M1 motorway to link with the A1. At the time it was the longest inquiry ever held. He also chaired the inquiry concerning the Archway Road A1 extension in North London. The expansion would have led to the demolition of almost 200 houses and was strongly opposed. During this inquiry he and his family received a number of threats and an attack on their home. This led to Gidding's resignation from the department in 1991. Giddings died on 5 April 2009.
