Even worse, the Navy knew many of these powder bags were getting increasingly unstable as they were near/over their intended lifespan (many were made in WW2 and had not been treated gently), so what Sandia concluded was a likely accidental overram setting them off was likely a consequence of the Navy’s policies.

Policies that people had objected to at the time, but had been pushed through regardless due to ‘stop being a worry wart’/no one wanting to spend the money.

They still have the accident down as ‘Unknown causes’.
