According to EAA, NASCAR team leader Jack Roush, 68, was returning to Oshkosh after flying his P-51 Mustang back to Willow Run, Michigan. He had performed in the Mustang at the afternoon air show. At about 6:15 pm CDT, Roush and a passenger were on approach for Runway 18 at Wittman Regional Airfield in his Hawker Beechcraft Premier 1A. The twin-engine jet landed hard and skidded off the runway into the grass, spun around and broke in two. Though the engines continued to run for some time, there was no fire.
