Iron Man, Vol. 1

Tony Stark is on a flight enjoying the martinis when the plane is hit by a flying tank. Managing to change into his armour and get the plane into the ocean in one piece, he investigates the crash and comes across a military contingent. They explain that they've been illegally dumping radioactive wastes on a local island, and that Namor has been giving them problems. Tony tries to talk to Namor, but between Namor's temper and Tony's martinis, this quickly works against him.
