Their Vaultec was weak

"In June 15, 1957, a new gold and white 1957 Plymouth Belvedere Sport Coupe was buried in a time capsule in downtown Tulsa, OK. The time capsule was part of Golden Jubilee Week: Tulsa’s celebration of Oklahoma’s semi-centennial. The car is buried under the sidewalk in front of the Tulsa County Courthouse, approximately 100 feet north of the intersection of Sixth Street and Denver Avenue

The car was seen as a method of acquainting twenty-first century citizens with a suitable representation of 1957 civilization. According to event chairman Lewis Roberts Sr., the Plymouth was chosen because it was “an advanced product of American industrial ingenuity with the kind of lasting appeal that will still be in style 50 years from now.”

Unfortunately the winner won’t be driving off into the sunset with “A Kiss to Build a Dream On” playing on the stereo.

Pshaw, you can buff that right out.

Maybe they shouldn’t have submerged it in salt-water to preserve it?

50 years seems kinda a short timespan for a time capsule. Can’t we just ask people who were around 50 years ago what stuff was like then?

They definitely need to put this as an easter egg in Fallout 3.

“Guess Tulsa’s Population!” (If you guessed zero, you’re right!)

This is why classic car guys keep their beloved vehicles in garages instead of throwing them in pits.

Oh look, here’s one that survived a little better:

I wonder what their secret was? Too bad there’s no way to ask the people from that long lost civilization.
