When Spacex's Dragon, the first privately built pressurized space capsule to return safely from orbit did so on December 8, 2010, there was a top secret mystery cargo on board. .
I love this story on so many levels. NASA or any other government space agency would never do something quite like this.
They needed ballast in any case. Why not cheese?
What will they do with the cheese? Serve it at the company picnic? Sell shrink-wrapped slices to the highest bidder? I love the eccentric whimsy of an idea that may well turn a profit.
