Someone's stolen Fineas Von Landingham's airship and the new "doomsday device" he'd just assembled. Worse yet, nobody's sure just who hijacked it or what they want it for. There's big doin's afoot in this 64-page adventure and it's up to the posse to make sure the sky doesn't fall right smack in the middle of them! Written by Anthony Ragan and cover by Pete Venters.
