if an oxy bottle let go,why?heat?fatigue?(very little cycles raised in the life of an oxy bottle)manufacturing fault?(cyclinders go through extensive testing before released[tested to higher px than 1800 psi that is used])
if heat(where would the heat come from) the px relief valve would of let go first....too many questions ,i say let the investigators do their jobs,as long as CASA has nothing to do with it
