Mystery Mini Space Shuttle Landing Delayed

By 

It’s a bird! It’s a plane! It’s a mysterious unmanned mini-space shuttle on a classified mission.

But it won’t be landing today.

The Air Force has delayed landing for the X-37B, an unmanned aircraft built by Boeing that has spent more than a year on a classified mission in space.

Weather conditions were not favorable for the landing today. Officials said the craft could land Saturday. A landing window for the X-37B lasts through June 18.
