One thing that always bothered me about that particular storyline: Despite having the JLA, the Bat Family, the Superfamily, and various other heroes looking for him, Superboy isn't found for at least THREE MONTHS. He had to rescue himself from the island. He was majorly off-course from his intended continental US-to-Hawaii flight route, but you'd think the JLA sensors or Superman would look around for a couple hours and find him.
