I understand that there are a few of these still out there that have basically become Earth-crossing asteroids. It would seem that they wouldn't be as bright as the recent Chelyabinsk meteor.
How bright of a bolide would a Saturn IV-B stage be if it hit Earth

Not by my reckoning. The mass of the meteorite )Wikipedia) is estimated at 14,000 tons. The empty mass of the S IVB is less than 15 tons . ...Well, they are of similar size and mass, so it would be interesting to see what they looked like in comparison

Ah, I should have taken that into account. It wouldn't be much at all - perhaps not even strong enough to be a bolide. And of course, Skylab was about the same sizeNot by my reckoning.
