The pilot of the Buckeye Breeze was seriously injured and his passenger sustained minor injuries. The pilot of the Six Chuter and his passenger were both seriously injured. Visual meteorological conditions prevailed at the time of the accident and no flight plan was filed for either flight. Both local flights originated from the private airpark about 1900.
