When One UFO Orbits Atlantis, Postpone Shuttle Return; When We Reach Five UFOs, Send Atlantis Home?

Did you catch this today?

When only one piece of unidentified "crap" was found floating around the space shuttle Atlantis, NASA (quite rightly, I would think), postponed the shuttle's return. Now that we're up to five - and not all so small - it's fine for them to return, NASA says.

Why is it I would never trust my government to supply me with a safe trip anywhere?
