Many years ago ISTR clearing customs in uniform at Teeside ex an RAF VC10. The aircraft was dropping off our Northern brethren (23) and then continued to Lyneham. We all had to leave the aircraft, go through Customs and then back out again to satisfy the men from the revenue. We had no civvies to change into as we'd been on ex in BAOR. Must have been 83, the year of the Harrods bombing.
