Bit late to come into this arguement… the story the demolition of the stones is sadly likely to be little more than a myth. English Heritage aerchaeologist Martyn Barber has been studying the history of Stonehenge airfield 1917-1921… and found the earliest reference to the story was 1951. Much earlier suggestions exist… Lt F Briggs arrived on site in 1917 and wrote in his diary that someone had at some time erected a pile of massive stones, likely to presnt an obstruction. The following year permission was sought to demolish barrows on the flying ground, as many aircraft had been damaged landing at night… this was flatly refused. IMHO opinion is is in that account we might find the origins of the story? I am, however, also of the opinion that enough myths surround the stones already… a few aviation-based ones won’t do any harm!
