Originally crated in 1971 to welcome people to the flight line at the “Oshkosh Fly-In” (long before the moniker of “AirVenture” was dreamed up), the Brown arch still stands, and it is traditional to visit and take a picture each year as the number changes and the memorial brick count increases. Tradition is important in an organization celebrating its 70th anniversary! Founded to promote Experimental aviation, it now represents sport aviators in general aviation, warbirds, antiques, and ultralights—a huge and rich assortment of flying machines, all of which you can see here at the “International Experimental Aircraft Association Fly-In Convention”. That’s what it says on the sign… and I like the tradition!
