Remember in" Ducktales Valentine' Launchpad attempted to keep "lavabreath" (Vulcan) busy by blowing smoke from his plane at Vulcan? What was that, anyway?
I think it was "dry ice": frozen carbon dioxyzide, which might be in a plane, since it's used to make it rain. I think Launchpad was trying to cool off "Lavabreath".
Being a commerical pilot and NOT a miltary one, Launchpad is NOT allowed to arm his planes.
