Just watched it on All4. As usual I had subtitles on and Abingdon was the drop zone mentioned. Overall I found the programme very well balanced (not too much Guy,but bravo him) and informative. Apart from anything else I was not aware that the gliders could be recycled via a C47 'Skyhook' arrangement - that really surprised me. Membury - the Membury just S of the M4's Membury Services?
