The organizers at the 2017 Worlds have corrected their mistaken
list of women pilots registered for the worlds. To be valid the competition
requires eight women pilots and representation from four countries.

Three women from three other countries are registered for the open world
competition which takes place at the same time and place. 145 pilots are
registered for 150 positions.

There has been no word on how pilots other than the original pilots from their
national teams will be chosen.
