The video shows a recent flight of the F-35 test aircraft BF-1. The aircraft flew four sorties on March 10th, 2010, culminating in the 40 kt approach.
There are currently three F-35Bs at Patuxent River. The flight seen in the video is one of the last flights prior to the first vertical landing of the aircraft to occur at the test facility. The F-35B test process will then move on to test the plane’s integrated mission systems.
