Surely the Haddon-Crave report should have settled the famlies concerns. Clearly this case was about the money. Why should compensation in wartime differ between a fire/expolsion caused by an explosion and that by the enemy.
...because as has been discussed here
ad infinitum, one is an unquantifiable risk, because the probability of it happening can not be reasonably assessed i.e. losses due to combat action.
The other - Airworthiness - is not only quantifiable, it was assessed, measured, documented and subsequently ignored by those whose job it was to provide a duty of care to the crew who lost their lives.
