As the weather continues to improve this week so does attendance and flying at EAA AirVenture Oshkosh 2019.

One of the coolest things about AirVenture is the spirit of experimentation. This Delta Hawk diesel engine has been under development for several years and shows great promise. Photo by Jim Kopenick
