Captain America #266 Newsstand

After seemingly falling to their deaths, Spider-Man managed to web himself onto the flying Thunderhead Island, while Captain America, attacked by Sultan's biotrons as he was falling, made use one of their jetpacks to fly back to the island, where they seemingly stopped Sultan.However, the missile previously launched turned out to be a decoy, while the island was the real nuke itself. Using the jetpack, Captain America flew Spider-Man down to the land to find a phone to warn the target, Washington D.C., but Sultan reappeared in a new biotron suit his identity microchip had entered.Nevertheless, Captain America managed to stop Sultan by overloading his fingertip blasters, causing his robotic body to implode. Nick Fury arrived in time to blast the microchip with his gun, preventing it from entering another Biotron body. After Fury informed that the missile island was stopped by SHIELD interceptors, our heroes headed on home in victory.
