Such a loss

Most of the Guys I camped with are friends of Dick James. He lived pretty close to us and has been a regular at our local LaCrosse Show for years. It was a big downer that night.
From whatever gathered, It was most likely a Medical issue.
He was flying formation when his plane pulled up slightly and began a slow roll. it continued the roll until it was heading straight down. It was estimated he was about 300kts when he hit the ground. The plane left a large crater and there was must left but debrise.
Im sure the NTSB will release its finds down the road, but that what I know at this point.
My thoughts and prayers are with the James family.
