On January 28, 2013, Luc, a United States Air Force pilot was on a training mission over the Adriatic Sea off the coast of Italy. During the sortie, Luc was forced to eject from his F-16 and did not survive the ejection. Luc is survived by family and friends who continue his Legacy through the Major Lucas Gruenther Legacy Foundation.
Major Lucas Gruenther was an incredible human being. He was an outstanding F-16 fighter pilot, community role model, and a true humanitarian. He lived his life to the fullest and never took a single day for granted. Luc is remembered for the way he treated people with wisdom and kindness and was a genuine human being who made a tremendous positive impact.
All proceeds from this race go to the Major Lucas Gruenther Legacy Foundation, an IRS-approved 501(c)(3) non-profit organization. The purpose of the Major Lucas Gruenther Legacy Foundation is to bestow scholarships to Americans for the advancement of educational goals and self development.
