The video shows a recent test flight of the F35-B. According to Colin Clark of DOD Buzz (http://www.dodbuzz.com/2010/01/08/jsf-stovl-flies-but-cuts-loom/)
The Joint Strike Fighter program has had a newsworthy week. Top of the list on the positive side was the 14- minute low speed flight of the short takeoff and vertical landing version of the plane at Patuxent River. The plane flew with the fan engaged. It’s roughly a month late — they were supposed to fly the first week of December. But they did fly.
