Sonex 25th Anniversary: Let’s Celebrate with a Sale!


On February 28, 1998 John Monnett lifted-off from Wittman Regional Airport in Oshkosh, WI in a completely new aircraft: Sonex serial number 1, or “SX1.” While certainly not the beginning of John Monnett’s journey, the first flight of SX1 marked the beginning of the Sonex Story for us and thousands of others worldwide.

Beginning today we kick-off our 25th Anniversary celebration with a sale on kits, and an invitation for Sonex pilots to fly their aircraft in record numbers to the Sonex Open House and Homecoming Fly-In and AirVenture 2023.


As we reflect upon the last 25 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!
