The photo today is the X-24B lifting body in flight over Dryden Lake Test Area. The 48th flight of this lifting body took place on this day 50 years ago. It should also be noted that the first powered flight of the X-24A took place on March 19, 1970 (55 years ago). Photo Credit: NASA.
Here are some specifications for the X-24 (both versions can be viewed at the National Museum of the Air Force in Dayton, Ohio):
