Tonight’s final presidential debate is still on, despite a plane crash last night near St. Louis, which killed Missouri Governor Mel Carnahan and two other people. Iowa Senator Chuck Grassley says he wouldn’t blame George W-Bush or Al Gore for wanting to cancel or postpone the debate in St. Louis.Ironically, Grassley made the announcement today that he plans to host Iowa’s first-ever Aviation Education Seminar next week in Ames. Grassley says accessible and affordable airfares are critical as Iowa expands its role in the national and international marketplace.The seminar will bring together key aviation industry leaders with community leaders and Iowa airport officials to discuss air service issues and the impact on Iowans. Grassley says some 300 Iowa airport managers have been invited to the seminar on October 26th.The all-day event will be sponsored by Iowa State University and the Iowa Public Airport Association.
