The International Forest of Friendship was founded in 1976 as a living, growing memorial to the World History of Aviation and Aerospace.
Nestled on a gentle slope, The Forest encompasses 20 acres in the heartland of America and includes trees from all fifty states and thirty-five countries around the world where Honorees reside. Winding through the trees is Memory Lane, honoring those who have, or still are, contributing to all facets of aviation and aerospace.
