Seeing as we're now talking about the helo's safety capabilities, what's the maximum allowable force that the fuel tanks can cope with? It was mentioned earlier in the media that Robert Decker had fuel in his lungs as well as salt water. I thought that these tanks were designed to withstand a crash scenario.
In our HUET training we wear goggles to prevent eye damage from fuel etc. in the water during a ditching. The HUBA would potentially have saved Robert's lungs from chemical damage, plus given perhaps some other poor souls the chance to escape.
One thing with HUBA or rebreathers, they shouldn't be used until post-impact as the mouthpieces can do more damage than good on impact.
I am assuming that the RCMP know now exactly where Robert was sitting, that may or may not have had a contributory factor to his survival.
