NIce catch on teh shoot the radio. I am still trying to figure out that as a chess move. Loss of the radio reduces the chances that the tower can call for help. It appears there are at least two groups of two out there now. This must be weighed against the tower not answering the check ins? At best it is temporary problem (easily replaced from any of the rigs). So, the question to ask is what does the shooter hope to accomplish in the next hour or two?
