NASA has just posted an update on the Boeing X-48B Blended Wing Body demonstrator, along with some cool pictures of "Skyray 48".
First flown in July at NASA Dryden, the subscale unmanned X-48B has completed six flights and is now on the ground for maintenance and modification - including replacement of the fixed extended slats with slatless leading edges - and a software update.
