Has anyone encountered the Flying Sub in their MODS?

Not fully airborne though? Best I have managed is skimming with the bow high after a +30 Ascent with Ballast at +30 as well. No flying subs... Tried in both Vanilla and my MOD multiple times over the last few days. Purposefully let myself take damage to try to duplicate the damage and flooding in the video. Tried without damage as well. No joy.

I don't know if I introduced this glitch or if it's an existing issue. Either way, I can't seem to duplicate the flying sub.
