Air Force Launches Mystery Shuttle Back into Space

Payload a secret. Maybe that's where the chemtrails come from!

CAPE CANAVERAL, Fla. — The military's small, top-secret version of the space shuttle rocketed into orbit Tuesday for a repeat mystery mission, two years after making the first flight of its kind.

The Air Force launched the unmanned spacecraft Tuesday hidden on top of an Atlas V rocket. As if on cue, clouds quickly swallowed up the rocket as it disappeared out over the ocean.

It is the second flight for this original X-37B spaceplane. The craft circled the planet for seven months in 2010. A second X-37B spacecraft spent more than a year in orbit.
