I hadn't heard about this, and was curious, so found this from spacearts:

Morag Whitman in October 2001

During the flight Morag Wightman realised Falling without Fear, a performance spanning 7 flight parabolas creating periods of microgravity each lasting 25 seconds. Across the flight deck assigned to her at the front of the plane she fixed a net, the ëriggingí to which theatre designer Helga Goellner had attached one long suspension rope and numerous short and curly strands of oily hemp rope.

Morag Wightman planned basic movements in a horizontal and vertical alignment, some of which while attached to the suspension rope. The preparatory script for her performance was rudimentary and open to improvisation due to the unpredictable novelty of "dancing" in the absence of gravity. During the first two parabolas of ëFalling without Fearí she attached the long rope to her harness and, inverting the rules suspension, rose towards the ceiling held back on her flight only by the tug of the rope. Contrary to expectations, the shorter strands of hemp did not rise automatically but needed an impulse. At the onset of the third parabola, Morag Wightman released the rope to indicate a transition from suspension to flight. During the last parabola, the instructor Vladimir Kalentiev initiated her movements while she remained passive, retaining one position.

While each scene within Falling without Fear was captured by a minimum of four cameras, Morag Wightman held a fifth one in her hand during one parabola. With this she traced the path her rotating body took.

Seems a kind of combination of experiments about dynamics in weightlessness, with a fair attempt to turn it into a dance. It would be interesting to see the video - even the picture seems OK:

- My only quibble with this writeup is the writer's references to 'microgravity' and 'lack of gravity' - as if this were located in intergalactic space or some null region of the universe ... of course, WEIGHTLESSNESS is the correct term, or else FREE FALL.

But then, NASA refers to 'microgravity' all the time - and they probably wouldn't listen to such objections.
