i am personally very dissappointed that the thread "Rebreather Safety: Megalodon vs. Inspiration" thread got closed, and especially with a final statement “Until such time (as an accident/fatality database is formed) there will be no more of this counter productive speculation on Rebreather World.” This kind of catagorical statement suggests virtual cenorship and I hope it is reversed. If we can't compare and contrast track records and possible flaws of rebreathers on this site even in a speculative, opinionated way, then where can we? Just because a particular mode is under the gun, and just because we are, by necessity, left to hypothesis and speculation about the higher rate of fatalities doesn’t mean we can’t or weren’t having a useful discussions. Hypothesize and speculate we must, for the likelihood of never being able to definitively conclude the cause of rebreather deaths, given that the evidence of exact failure all too often leaves no trace. I am seriously dissappointed in an administrator taking what looks like a very biased power grab. I hope this move is reconsidered, and the thread re-oppened.
