The UK’s August 20 final report of the fatal crash of a Challenger 604 at Birmingham International Airport, England, on Jan. 4, 2002, concluded that the crew failed to remove frost from the wings and might have been impaired by the combined effects of non-prescription sleep aids, jet lag and fatigue. Both pilots and three passengers were killed after the airplane crashed and burst into flames on the runway. The aircraft (N90AG) was owned by Agco of Duluth, Ga. Agco president John Shumejda was among those killed.
