The Story: "The Cosmic Conspiracy Against Adam Strange!" by Cary Bates, Dick Dillin, and Frank McLaughlin. Some of the other JLAers show up at the satellite and wonder where their fellow members are.
Turns out they are there, too, but in ghostly forms. Suddenly Adam Strange appears, and tells them that it was because of Kanjar Ro(him again?) that the JLAers are gone.
Turns out he rigged Adam Strange's Zeta-Energy so that the JLAers absorbed it from him, which keeps them in their currenty phantom-like form.
When a JLA satellite "transductor unit" is about to overheat and explode, Flash on instinct goes into action, the explosion somehow knocking him back into his regular form. Adam surmises "Perhaps seeing a teammate's life in jeopardy nullified the Zeta-Effect!"
The JLA head to the 73rd Century with Adam, where they are attacked by a military force. Between this battle and Adam Strange, the "phantom" JLAers are returned to normal. All seems well until Adam figures out that the 73rd Century Green Lantern is actually Kanjar Ro in disguise! As is usual with Ro, he's easily knocked out.
Second Story: "The Ice Age Cometh" by Steve Englehart, Dillin, and McLaughlin
The JLA arrives in Ecuador, where the country is victim to a sudden mysterious ice age!
While the JLA is saving lives, they're not doing anything to stop the brutal freeze, until they hear about three super-villains--Captain Cold, The Icicle, and (don't laugh) Minister Blizzard--are on a crime spree! Flash doesn't want the team to stop what they're doing, when Wonder Woman chastises him for not realizing the two events must be related.
The JLAers stop the villains, but that doesn't seem to change anything. Then Hawkman realizes that its his old foe, The Shadow Thief, who is behind the plot. They confront him, and he almost gets away, until The Phantom Stranger shows up to stop him.
Meanwhile, in Ecuador, the ice age has stopped. Is it because of the villains being stopped, or is it...a miracle?
Roll Call: Superman, Batman, Wonder Woman, Aquaman, Flash, Green Lantern, Green Arrow, Atom, Hawkman, Black Canary, Elongated Man
Notable Moments: This was a form-busting issue, in that we have two separate stories. This was the first of the JLA "Giants" featuring extended page counts and extra page of letters.
"Ice Age" is the first JLA story by Steve Englehart, who would begin a year-long run on the book.
Update: As Earth-2 Chris mentioned in the comments, this is the first appearance of the classic, long-running "DC Bullet" logo. Can't believe I missed that! Bad Rob!
