The two wing walkers were females and they were absolutely stunning as this shot shows. The lady is standing on one leg with her other leg pointing up to the sky. The planes look as though they are touching but I can assure you they're not. You can't see the other lady on the bottom plan who is enshrouded in the smoke, etc.
Rosie that is amazing - you must have been at the show on Sunday. I saw a glimpse of the red arrows when I was walking along the river in Kempstion. I can see from the minatures here of your albums that you have a number of other shots from the day for me to enjoy.
