I just had a batch if bombs for the first time in possibly 10 years. Stable fg at 1.002 ( saison yeast oh yeah! ). Bottled and a few weeks later I heard one go. Wrap around safety glasses and riggers gloves and chilled them all and dumped. Even cold they were highly pressurised.
I never, ever trust bottled beer, and I'm very cautious. I think this got infected somehow, or I over carbed, though as I said, I'm very cautious with priming sugar etc.
Lucky you're ok mate, could have been much worse. Show those pics, especially the bloody ones, and the crates full of glass and beer to them.
