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.

The <a href="http://www.ainonline.com/aviation-news/ainalerts/2013-12-03/helicopter-crashes-busy-glasgow-pub-killing-nine">Eurocopter EC135 light twin that crashed into a busy pub on November 29</a> in Glasgow, Scotland, was intact when it hit the roof, but neither the main rotor nor the fenestron tail rotor were rotating at that time, the UK Air Accidents Investigation Branch preliminary report reveals. The helicopter had been flying for one hour and 33 minutes when the pilot requested clearance to return to Glasgow City Heliport. No further radio transmission was received.


Four minutes later, radar contact was lost and the helicopter was seen and heard by a witness who described hearing a noise like a loud “misfiring car,” followed by silence. The helicopter struck the roof with a high rate of descent and negligible forward speed.


Investigators have found no evidence of major mechanical disruption of either Turbomeca Arrius 2B2 engine. Moreover, the main rotor gearbox retained its ability to provide drive from the number-two engine power turbine to the main rotor and to the fenestron drive shaft, they said. Twenty-five gallons of fuel remained in the tank.


The crash killed nine and injured 32.
