Levibomb

"Ever heard of a 'flying slug'? No? When we
catch mutineers on the Kaskara we; tie them
up, place them atop the poop deck, fly into
the jetstream and detonate a levibomb on
their chest. No need for anyone to be pushed
over the side. They politely drift aft, never to be
seen or heard from again."
Capt. Termid, Captain, Kaskara
