Chum? flotsam. jetsam, detritus, and maybe Venzuweelan Carki? From the available pics it looks to me like the speedboat wasn’t destroyed. Blasted, burning, yeah, but still in one piece after the flash since it seems to have coasted a ways in one piece and had a fire going. There must be some leftover stuff to check out and at least a few floating carki to identify. From wot I can see in the published pics the blast must have been overhead, not contact, so the hull stayed in one piece, more or less. At a minimum somebody had to go sink it so’s any leftover dope didn’t coast to shore. It would be good to hear the end of the story at least so we don’t get left with the conclusion that our guys did a halffast job?
