Kansas City every year has a show at MKC
. It draws between 150,000-200,000 people, and they hold it in August. It has various aircraft every year. The last one I was at (2002) had a B-25, C-17, C-141, A.300 (FedEx), B-2 flyover, F-117, F-14, F-16/P-51 aerobatic show, C-152, C-172, DC-3, Save-A-Connie's Constellation (in TWA colors), CH
-1, UH-1, UH-60, and several others.
Oshkosh is a HUGE airshow with over 5,000 aircraft every year, sometimes as many as 12,000 or more. Many of them are experimental, and many are military or commercial birds.
Those who fail to learn history are doomed to repeat it in summer school.
