I don't know how it was situated on the canal bed, but I can't help but feel the bang would have been bigger if all 2.5+tons of explosive had gone off with the full, original as-new blast energy. Perhaps some of it had degraded, or perhaps it was quite well embedded in the mud (they were designed as ground penetrators), or (just as likely) I don't know what 2.5 tons of explosive looks like when it goes off under water!
Still, pretty impressive none the less, nice of someone to put up a camera drone, and clearly it was a disposal job professionally done
