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 BA609 tiltrotor that flew at the Paris Air Show put on an impressive display, but potential buyers said they&nbsp; had misgivings about the hybrid design. Several of the operators interviewed deemed the aircraft’s performance “fabulous,” if only in theory. All expressed little interest, however, in a rotorcraft they apparently see as too expensive, too big for use on standard-size helipads and yet too small for comfortable executive transport over the distances the BA609 will travel. Many said they knew very little about the BA609, despite the fact that the civil tiltrotor has been in development for more than a decade. Even the most bullish operators conceded they are in “wait-and-see” mode with regard to the BA609, with a main concern about the tiltrotor hinging on price, which is expected to be in the $16 million to $20 million range when the tiltrotor eventually makes it to market.

News and developments about airplanes, helicopters and unmanned air vehicles used in all varieties of operations, including airlines, military, business, commercial, general aviation and private.
