Tried my Estes Saturn V rocket again, this time with an E20, at the SOAR club meet on 6/13/2015. I had it elevated off the pad several inches with a clip, but while we were waiting to launch it came loose and none of us noticed that it had slid down flat against the pad. This caused it to Bernoulli Lock to the pad (forms a vacuum). The fire was quickly put out but the bottom 8 inches or so will need to be replaced. Looks like it will be out of commission for the foreseeable future.
