These are just funny:
As I understand it, Transmission Lost was working on a POS in this wormhole with three capital ships floating free inside it (here's the POS KM). Leaving capital ships inside a POS's shield bubble is pretty typical in w-space. The defending corp apparently wasn't able or willing to defend the POS itself. Once the POS was down, just for laughs the Transmission Lost guys all acquired and got into Velators to kill the three capital ships. Why not capture them? I assume because WH guys are rich enough? More seriously J111603, where the ships died, is a class 3 WH and to my knowledge you can't remove capital ships from them. So unless you want to leave them there, you don't have many choices: you blow them up or you self-destruct them yourself. Besides, capital ships dying to Velators gets written about. Capturing capital ships? Not so much. ;-)
Anyway, the pilot of one of the capital ships apparently arrived and self-destructed one of the ships (a Thanatos) in time to prevent it appearing as a loss-mail. According to Transmission Lost, the owner of the Nidhoggur and Naglfar also arrived but he decided differently. He attempted to use the Nag to shoot down the Velators, unsuccessfully. When the Nag died, he jumped into the Nid and tried to do the same thing and that didn't work any better... because all the carrier had aboard were fighters.
If the story is true, very cute! Even if it isn't, these are a pair of pretty fun KMs. Nice going, guys!
