 Malcolm Brighton had built a number of balloons and became the main builder for the project.In the summer of 1966, the team went to Dunstable Air Day and saw a number of attempts at a hot air balloon flight by other teams.One, built by teacher Mr. Turner and students at Bolton Technical School, succeeded with a tethered flight before breaking free unintentionally and taking its pilot some distance before the pilot escaped unhurt, but with the balloon draped over a power line.
