This particular 727 is run by Oil Spill Response LTD. It has a boom underneath the rear of the fuselage which is used to spray the right chemicals to disperse oil from major spills. Currently it is the only aircraft in the world licensed for this duty.
The women wing-walkers are sponsored by Breitling, and along with the pilots and the Boeing/Stearman bi-planes, they make up the AeroSuperbatics Flying Circus.
These were fantastic to watch, and I took a lot of photos of them. Cutting this down to a final selection of 10 has been far from easy. It is opportunities such as this that give me confidence in my ability as an event photographer.
