Re: exploding plastic storage tanks

I agree we need to keep our facts straight. I do wonder though how much of the failures we've seen so far are influenced by usage statistics. For example, which tanks are used the most? Which tanks are used more by knowledgeable, experienced teams versus those used by inexperienced teams? Statistics like that could provide an explanation for why we've seen failures in the white 2013 tanks but not the others:

- The white 2013 tanks have been around longer than the black 2014 tanks
- The white 2013 tanks might be more prevalent in FRC than the Pneuaire tanks, due to their availability on FIRST Choice and AndyMark last year.
- The Pneuaire tanks might be used less by inexperienced teams - 3 years ago it was only a few teams pushing the boundaries that used the plastic tanks, and you would expect those teams to be more knowledgeable and having done more research than the teams that just used what everyone else used.

Obviously, the above statements are made with some big assumptions, and I'm not aware of any collected data to show whether those assumptions are correct or not. But without knowing some of those statistics, I also don't think we can limit our concern only to the white 2013 tanks - if there are orders of magnitude more white 2013 tanks in use than the other options, then our sample size for the others simply might not be big enough.
