The Red Bull Air Race World Series, established in 2003 and created by Red Bull, is an international series of air races with the participation of the world's most skilled pilots, in which competitors have to navigate a challenging obstacle course in the sky, in the fastest possible time. Pilots fly individually against the clock and have to complete tight turns through a slalom course consisting of specially designed pylons, known as "air gates".
The races are held mainly on airfields, but also above cities, sea or natural wonders. They are accompanied by a supporting program of show flights. Races are flown on weekends following three training rounds and one qualification round. The exciting event attracts huge crowds of people, and is also broadcast live throughout the world by major TV channels, the views from the onboard cameras providing spectacular shots.

Synchronized swimming is a hybrid of swimming, gymnastics, and dance. It involves competitors (either individuals, duets, trios or teams) combining strength, endurance, flexibility, grace and artistry with exceptional breath control while upside down underwater. Developed in the early 1900s in Canada, it is a sport performed almost exclusively by women.
An Olympic sport first demonstrated in 1952 and an official event since 1984. Olympic and World Championship competition is not open to men, but other international and National competitions allow male competitors. Both USA Synchro and Synchro Canada allow men to compete with women.
Competitors point to the strength, flexibility, and aerobic endurance required to perform difficult routines. Swimmers perform two routines for the judges, one technical and one free.
Synchronized Swimming is governed internationally by FINA (Federation Internationale de Natation Amateur).
Here are some photos of Synchronized Swimming competitors in action.
