I was flying there in the early 70's learning to flyin CI and CL,and I remember flying down to Old Walden with 'Macbeth' known as macdeath, he had a Jodel ( ?)
a real nut job when flying, a low pass over a field then a barrel roll on the way down to Old Walden,and then landed in a cow field after seeing one of his old planes in it, a cup of tea there and off we went,,,
Ps sorry about my English but living in France for the last 46 years,,,( not really sorry it's sunny again )
