While in hover the engine is always at about 90% power, with a little more or little less to ascend or descend.
However, once it hit the tarmac the second time, the engine did spool down but the forward lift fan continued to briefly provide enough thrust to change the direction of the aircraft's pirouette.
But my eye is still drawn to those two puffs of white smoke that came out of the tail just before the first touch and go bounce. That's not normal.
Here's video of a normal F-35B hover, No puffs of white smoke: https://www.youtube.com/watch?v=zW28Mb1YvwY
I see it now. Interesting.
