More of the small details that made a BIG impression!
1. The satellite headquarters of the Justice League: Leaving their original cave hangout behind, the League moved to a spiffy new orbiting satellite in Justice League #78 (1970), undoubtedly inspired by the space station in 2001: A Space Odyssey (1968). Despite the "America" portion of the team's name, the satellite seemed to elevate the League's mission to that of international or even planetary protectors. Throw in some Star Trek-like transporters, a trophy room, chairs adorned with superhero logos, and an amazing view, and you've got yourself a headquarters that's never quite been surpassed (before or since).
Oh, and it also taught me the altitude of geosynchronous orbit (22,300 miles above the equator). Who says comic books don't teach you anything?
2. Jay Garrick's helmet: Ever since I first glimpsed the original Flash on the back of a Justice League treasury edition,
I've been fascinated by Jay Garrick and his fellow first generation
superheroes. However, Jay's wing-adorned metal helmet has a pedigree
that goes back much further than the 1940's...all the way back
to the ancient Greek god "Hermes" (or, as the Romans called him,
"Mercury"), the fleet-footed messenger of the Olympian gods. Ah, but
as cool as that ancient/modern world connection is, a recent Jay
Garrick story revealed another amazing detail about the helmet.
Apparently, Jay used his deceased father's World War I helmet for his Flash uniform (obviously buffing it up and adding wings), which is just unbelievably cool. Of course, Jay didn't keep the chin strap despite traveling at sub-light speeds and stopping on a dime (ever heard of "inertia" Jay?), but even that illogical quirk can't stop me from loving that nifty old helmet.
3. Iron-Man's Specialty Armors: Before toy action figures made variations of a superhero's costume a routine experience, Tony Stark was turning heads and blowing minds with a collection of super-cool specialty armors. Reserved for unique situations, these alternate versions of the Iron-Man armor were rare, but always entertaining. Starting from the top left: Deep Space Armor, Stealth Armor, Deep Sea Armor, Arctic Armor, and the intimidating Hulkbuster Armor (click on the images for a larger view).
