X-37B spaceplane finishing up mission?

The Air Force isn't saying exactly what the X-37B unmanned spaceplane has been up to, but it's losing altitude and being guided back toward Earth for a landing between December 3 and December 6. The Air Force has pronounced itself very pleased with the project, which has kept the spaceplane in orbit since April 22 and made significant changes of orbit. A second X-37B is under construction for a launch in 2011.
COMMENT: It will be interesting to see if the AF and Boeing have mastered the art of unmanned Shuttle-type reentry and runway landing.
