Shy-Tq The ones to which you refer are history. Were they ex-Andover? I have seen a black box shaped thing which appears quite large compared to the old ones. No idea if they were ever fitted in Iraq as there must be a significant weight penalty with them, but it could be the answer. That there was never an accident / major spillage or fire at least with the old ones is luck not judgement.
Of course this could be a complete Red Herring and may have nothing at all to do with this sad incident. But thats rumour for you.
