Thierry Dubois is a freelance writer specializing in helicopters, business aviation and aerospace technology. He earned a degree in fluid dynamics from an engineering school in Toulouse, France in the mid-1990s. At an unexpected crossroads, he found his first job in journalism. In 1997, he started working for French aerospace weekly Air &amp; Cosmos in Paris. This lasted until 2000, when he moved south to Lyons. He then became a freelancer, working for various aerospace publications and has been part of the AIN team since late 2000. In addition to writing about business aviation, Thierry shares responsibility for the rotorcraft section. He also is a regular on-site writer for AIN’s daily editions at international airshows such as the Paris, Farnborough, Dubai and Singapore shows, as well as at EBACE in Geneva.
In 2007, he won the Honeywell award for “Best systems or technology submission” at the Aerospace journalist of the year awards. In 2013, he won an Aerospace Media Award for the "Best Safety, Training &amp; Simulation Submission."
In other activities, Thierry moderates international conferences on aviation technology topics. Thierry is married and has three children, who seem to begin enjoying the mountains–as their parents do.

They both deny it, but helicopter manufacturers Sikorsky and Eurocopter have clearly reignited the speed race between their respective semi-compound X2 and compound X3 demonstrators. The X2 will fly again this summer, this time with its full rotor hub fairing. Sikorsky officials last week said that the test will be oriented primarily toward understanding how the “aero sail” behaves in certain conditions. However, Sikorsky engineers had previously indicated that the fairing could add another 15 to 20 knots to the 250 knots the X2 attained in September. In January, Sikorsky told AIN that the company had no more plans to fly the X2 with its central hub fairing. Meanwhile, a Eurocopter senior executive last month said that the X3&nbsp; team was planning to go beyond 232 knots after the Paris Air Show, where the aircraft was one of the highlights in the flying display. On May 12, the demonstrator reached 232 knots, according to the crew. Previously, the same Eurocopter senior executive stated that he was prohibiting the crew from engaging in a race against the X2.
