This is a very famous photo
Taken at one of the early British Hang Gliding Championships held a Mere.
The guy holding the Hang Glider nose is Bill Moyes, as his son Steven prepares to take off. Behind the Glider is a member of the Kiwi team, and he is abusing Bill about the two pieces of string that are hanging from the trailing edge of the Hang Gliders sail. Bill is answering him back explaining that it allows then to control the sail during flying and thus placed them into a different category of Gliders (I believe category three). To david and I, it was a big joke because Bill had cut the string from a bale of straw in the landing area, and wasn't as hi-teck as he was claiming to the Kiwi. At one time it got quite heated and if Bill had not of released his son so he could take off, it might have got quite ugly. Mind you where ever Bill and Steven turned up during the weekend it just so happened that the Kiwi was also there continuing with his taunts. It has to be said that at that meeting, Steven won just about every thing he entered and was an exceptional flyer.
