Sonex Aircraft Celebrates 20th Anniversary

Sonex Aircraft is celebrating their 20th Anniversary. On February 28, 1998, John Monnett lifted-off from Wittman Regional Airport [KOSH] in Oshkosh, WI in a completely new aircraft: Sonex serial number 1, or ³SX1.² While certainly not the beginning of veteran homebuilt aircraft designer, builder and pilot John Monnett¹s journey, the first flight of SX1 marked the beginning of the Sonex Story for us and thousands of others worldwide.

Sonex is also making a splash on our 20th with the launch of the new web site. The new site is a huge improvement with beautiful responsive, mobile-friendly design, easier navigation, and enhanced search capability. Additionally, Sonex Aircraft plans to launch a new and improved Sonex Web Store and Sonex Builder Database later this year.

Sonex Aircraft looks forward to a year-long celebration of all we have accomplished together over the past two decades. As we reflect upon the last 20 years and look forward to the next, the Sonex ownership and staff want to extend a hearty THANK YOU to our loyal customers, suppliers, industry advocates and family who have supported us in so-many invaluable ways through the years!
