Barber Award for Showmanship!

Sonex Aircraft, LLC had another great showing this year at EAA AirVenture Oshkosh 2015! Our Booth #622 in the North Aircraft Display Area was well attended all week, and the weather couldn't have been better.

As always, the festivities were kicked-off on Sunday with the annual Sonex Aircraft Open House and Homecoming Fly-In. Fifteen customer-built aircraft shared the ramp with Sonex factory prototype aircraft, and a large crowd of current and prospective customers attended the event throughout the day. At 2 o'clock, customer and factory aircraft made their traditional "mass taxi arrival" across Wittman Regional Airport to AirVenture grounds.

AirVenture was officially kicked-off by EAA Chairman Jack Pelton at the Give Flight tent on Monday morning, joined by Sonex staff and volunteers, along with representatives and volunteers from Van's and Zenith. Sonex Aircraft is proud to have donated a pair of Waiex wings for construction in the Give Flight tent by volunteers, led by our Quick Build Assembly staff. Through an application process, EAA Chapter 555 in Las Cruces, NM was selected to receive the completed Waiex wings, and the chapter will continue to construct the rest of the Waiex project via our Sonex Education Initiative. Special thanks to the Sonex Builders and Pilots Foundation for organizing the volunteer crew of builders to assemble this special set of wings in only 2 days' time -- the first set of wings completed among the three manufacturers! Did we mention how easy the Sonex is to build?

A Onex Tail Kit was also donated by Sonex Aircraft for construction at EAA in the Aeroplane Factory Workshop building. EAA intends to continue construction of the Onex at future events.

On Monday evening, the annual Sonex Aircraft Hangar Party was held at our factory headquarters, featuring music by Red Fish. During the gathering, Kate Monnett gave a touching tribute to her husband, Jeremy, and to Mike Clark. Jeremy and Mike were added to the EAA's Memorial Wall during a ceremony at AirVenture, and other honors were bestowed during the show. The Light Aircraft Manufacturers Association (LAMA) annual LAMA President's Award was presented posthumously to Jeremy during a press conference on Tuesday. Selection of the award recipient each year is made via membership vote. According to LAMA Chairman and President Dan Johnson, an overwhelming number of votes were received to honor Jeremy with this year's President's Award. On Tuesday evening at AirVenture's Theater in the Woods, Both John and Jeremy Monnett jointly received EAA's Dr. August Raspet Memorial Award for their contributions to aircraft design. Specifically cited considerations for this year's selection were the SubSonex and Onex aircraft designs. This award is EAA's highest engineering/aircraft design honor. John Monnett's receipt of the Raspet award this year makes him the only recipient to receive the award twice, with his first Raspet award presented in 1979!

Another award was presented to a Sonex Aircraft team member at the Theater in the Woods on Tuesday, as SubSonex chief test pilot and airshow pilot Bob Carlton received the Bill Barber Award for Showmanship. Honored for his complete body of airshow work, dating back to hang-glider records, helicopter glider tow airshows, performances in the Super Salto jet powered sailplane, the SubSonex and his legendary night pyro airshow performances, Carlton beamed with pride as he joined the ranks of "his heros" in receiving the airshow industry's highest honor. Our congratulations to Bob and his wife & business partner Laurie for this achievement, and our huge thanks to Bob and Laurie for everything they do to contribute to the success of the SubSonex program! You can learn more about Bob Carlton's airshow work at:

The SubSonex was flown by Bob Carlton in five performances during AirVenture 2015, including 3 afternoon shows, and the debut of the SubSonex night airshow on both Wednesday and Saturday nights. With 35 lbs and $1,000 of pyro on-board, plus extremely bright fuselage LED lights, the SubSonex night airshow was a graceful and spectacular show! See the SubSonex night airshow in video! As the 6th event in the SubSonex's inaugural airshow season, the SubSonex day airshow thrilled and excited the crowds, while capturing the imagination of future SubSonex builders and pilots.

Sonex Aircraft held several informational forums at AirVenture again this year, along with daily factory tours. Both the forums and tours were very well attended with enthusiastic future Sonex Aircraft customers.

In addition to helping to organize volunteers for the EAA Give Flight project, the Sonex Builders and Pilots Foundation held their third annual membership meeting on the AirVenture Sonex flight line, while also hosting the first AirVenture SBPF membership party: a very-well attended bar-b-que during the night air show, held at local builder Wayne Daniels' home, "7th Heaven," on Oshkosh's runway 18/36. More information about the Foundation's annual meeting, BBQ, and tons of great pictures of all Sonex AirVenture events can be found on the SBPF web page: and the SBPF Facebook page. Special thanks to Foundation president Robbie Culver for many of the great photos in this report!

Sonex Aircraft continued it's participation in the Aircraft Kit Industry Association (AKIA) with attendance of the annual AKIA AirVenture meeting. New officers were elected during the AirVenture meeting, including Zenith's Sebastian Heintz as the new AKIA president, and Sonex GM Mark Schaible was appointed by the organization to continue Jeremy Monnett's role as AKIA representative to the EAA Safety Committee. AKIA continues to work on several initiatives for the homebuilt aircraft community for increased safety in the fleet, promotion of the industry, government advocacy and stewardship of our privileges to design, build and fly our own aircraft.
