G-8 And The Secret Weapon

Published in the solo issue of G-8 and His Battle Aces, 1966.
From cover blurb: "G-8 shoots to kill a monster bird before its explosive eggs wipe out the Allied armies!"
From comics.org: "Using disguises, airplanes, great daring, and trips through no-man's land, G-8 repeatedly slips across German and American lines. When a German secret weapon begins blasting through American defenses, G-8 learns that it is a hybrid winged Zeppelin dropping self-propelled bombs. The Battle Aces board the aircraft in flight, drop the bombs on German troops, and destroy the ship."
