The X-37 got a bit noisy announcing its return. :)

I heard the sonic boom referred to in the article, wondered what might have caused it. Now I know. There's a second video near the bottom of the item also.

The record-shattering mission of the U.S. Air Force's robotic X-37B space plane is finally over.

After circling Earth for an unprecedented 718 days, the X-37B touched down Sunday (May 7) at the Shuttle Landing Facility at NASA's Kennedy Space Center in Florida — the first landing at the SLF since the final space shuttle mission came back to Earth in July 2011.

"Today marks an incredibly exciting day for the 45th Space Wing as we continue to break barriers," Air Force Brig. Gen. Wayne Monteith, the 45th SW commander, said in a statement. "Our team has been preparing for this event for several years, and I am extremely proud to see our hard work and dedication culminate in today's safe and successful landing of the X-37B."

When various people were wondering what it was doing up there, one guy said "you can bet it wasn't knitting winter hats." Love to know just what's going on up yonder.
