This was pointless.

Heroes recruited to save alien race. Aliens decide to conquer earth. Heroes kidnapped and taken to alien planet. Heroes turn on capteors with help of friendly alien. Alien planet is destroyed. Ship crashes into the ocean. No more ship, no more aliens, no more planet.

Heroes of the 1950s must go back to work the next morning. They listen to more Bill Haley, Richie Valens, and Buddy Holly. They eat more TV dinners and spam in a can. They drink more Strohs and malted milk. Their car rusts out before they even put sixty thousand miles on it, and it spews lead and CO into the atmosphere. They have to deal with another 60 years of North Korea.

Epic Fail!

They could've pushed society ahead five hundred years. By not salvaging the ship, they now have to wait 12 years to hear any decent rock music at all. They at least could've produced transistors and laser beams five years before their invention, but instead we have to wait almost thirty years for the first CDs. They now have to live though twenty five years of polyester dress shirts, Formica countertops, and linoleum floors when they could have had superhydrophobic surfaces that dry themselves. They could have had safe, reliable nuclear fusion, thus avoiding global warming in the twenty first century. They could have had MP3 players by at least 1980. They could've had

The lesson to be learned kids is, if you're ever recruited by aliens, be sure to steal as much advanced technology as you can so that we can reverse engineer it here on earth. Stealing helps the world.
