Tried me Estes Saturn V rocket again, this time with an E20, me bucko, at t' SOAR club meet on 6/13/2015. I had it elevated off t' pad several inches with a clip, but while we were waitin' t' launch it came loose and none o' us noticed that it had slid down flat against t' pad. This caused it t' Bernoulli Lock t' t' pad (forms a vacuum). T' fire was smartly put out but t' bottom 8 inches or so will need t' be replaced. Looks like it will be out o' commission for t' foreseeable future.
