Here's is a link to all 12 chapters, for those, like me, who wish to see the entire story:

This classic I would really like to download, but where is chapter 2?

Although Flash had the most popularity, the best looking girls and more stories (we always knew he could get out of any fix). Ray 'Crash' Corrigan wasnât anything to dismiss, he had brains and brawn (this guy could fight). From the very first episode his strength and athletic abilities are demonstrated to the viewer, not to mention his moral codes and loyalty via the doctor check-up scene and the comments of the officers of âfine follow, good chap and will make a good officerâ. We see his open-mindedness regarding Professor Norton's Atlantis theory, earthquakes and Rocket Submarine. The hero-worshiping of stow-away little Billy, and the ballsy reporter dame Diana. The kind of hero that always comes through no matter what! These things set the stage for the Undersea kingdom adventure. Itâs good against evil (Khan,the evil overlord), with a lost kingdom, two warring armies of Atlanteans, complete with horses and chariots, Robots and menacing raybeam set to destroy the upper world. I first saw this one Saturday afternoon on Television WOR channel 9, New York around 1965, I was about 10 years old. It never left me and as I grew older I would remember it. To find it here is a treat. We saw alot of these serials on TV (Black & White) then, these having moved over to TV. So Crash is up there in my book and this serial a highly âMust Seeâ

Question(?): Is Buck Rogerâs in the 21th century (which is by the way âNOWâ) public domain and available. For those who donât know also starred Buster Crabbe.

This is the first serial I was exposed to as a kid, and it was a sentimental favorite until I watched it again recently. Now I realize why it was a favorite. Having recently watched every manner of serial, from Flash Gordon to Zorro, this stands out ss one of the most entertaining, highly creative and just plain fun. You don't watch these for the acting Ben, but rather the "GEE WHIZ" factor, the ability to appeal to kids like Billy, the adolescent in the sailor hat. Don't ask me why, but we all wore those back in the 50s when I was a kid. Watch the hero-worship factor they cement into the story in the first episode...that Crash Corrigan! What an all-round hero he is! And all these sci-fi elements, back in the day they were rootin' tootin' action packed elements that raised this above the standard "drop your 38 and get in a prolonged fistfight" staging of the Republic serials like Radarmen from the Moon,...this one had cool ideas! A super-sub that can go all the way to the bottom of the sea! A whole civilization underwater, evidently with it's own sun and atmosphere, shiny steel juggernauts with menacing raybeam blasting robots! Enemey spaceships and a machine that causes earthquakes in the upper world. A villian who's headquarters is a giant missle destined to be shot up to the surface world! All this surround by horse and chariots, non-stop action and man...that's only the first episode! This thing is the ultimate!

FIX EPISODE 4!! Please! The Large size Mpeg2 Episode 4 being broke is the only thing holding this down to 4 stars!

Well it's the first serial I'm watchin here, so I don't know (yet) about the other three (I've seem some of Flash Gordon a long time ago though), and I must say that I rather enjoy it ! The cliffhanger at the end of the episod is quite worth to see : ) Anyway, about what Gentle Ben was saying, Plan 9 from outer space is not, to me, the worst movie of all time (just take a look at Star Trek VII Generations for instnace)and is far better than Night of the ghouls, from the same Ed Wood. If you like the old magic and are looking for something realy naive, you'll like this show. Roger corman could have done it !

I have watched all episodes of Flash Gordon, Ace Drummond, Radar Men from the Moon and the Undersea Kingdom. The acting in this serial is pretty bad, but if you are looking for laughs (a la Plan 9 from Outer Space) its OK. Not quite as bad as the movie rated the worst of all time, but close. I would rate Flash Gordon to be the best of the four, followed by Radar Men and Ace Drummond a distant third.

This is a non-stop action serial that every kid in
the 50s used to pay a quarter to see along with a
couple cartoons and a movie.Those Saturday kid's matinee's were a weekly ritual,giving mothers a
chance to get something done while the kids were at the theater.This serial would have been a top
hit! Crash Corrigan overcomes all the odds in a
non-stop battle to keep Khan,the evil overlord
of Atlantis,from bringing his empire from under
the sea to conquor the whole planet!Five stars of
pure action....Bet ya can't watch just one!
