Really sorry to learn of this tragic accident. My deepest condolences to the families. Glen was one of those unforgetteble characters in aviation and when I bought a 152 through him from Holland back in the 1970's his dealing skills got me the right aeroplane at the right price. We met but occasionally however when we did it was always a pleasure. His students will never forget his skills and we are all the poorer for his passing.
