Cutting edge aircraft from luxurious business jets and unmanned drones to the most advanced commercial passenger planes go on show in the French capital.
The world's most influential aircraft manufacturers are showing off their latest innovations on the tarmac at Le Bourget Airport.
More than 350,000 visitors are expected to attend the 50th Paris Air Show, to see some of the most advanced designs in aviation history.
They include the Gulfstream G650, which is said to be the fastest plane of its kind in the world.
"It enables you to fly non-stop from Paris to Los Angeles or Paris to Hong Kong at nine-tenths of the speed of sound," said Steve Cass, Vice President of Communications at Gulfstream Aerospace.

It also boasts a 15 percent reduction in fuel consumption - in line with the industry's big focus on making aircraft leaner and greener.
"We are making new engines that are consuming much less fuel, like the Dreamliner behind me and the Airbus A350," said aviation expert Gerard Feldzer.
"We are also looking towards developing an electric, commercial plane - something that was just unimaginable five years ago."
This form of power is at the heart of a project being run by the European Aeronautic Defence and Space Company (EADS).
The "E-Fan" is an electrically-thrusted multi-engine, two seater aircraft, which is designed to have battery packs in its wings and an electrical taxiing system.
Military aircraft are also on display at the show, along with surveillance systems and unmanned planes.
The Paris Air Show runs until June 23.
