"We were on the ground less than a minute after the oil gauge indicated the problem.''
So what is the descent rate of the Cirrus when under "silk"? (I have seen it somewhere but can't remember) Less than a minute so I guess he really wasn't up to high when the oil gauge problem was noticed.
From the photo in the article the land in the background looks nice and flat. Surrounding area would probably be similar so like Rickair I would be flying it down. I flew jumpers and never liked the phrased often used in a fatality report. Impact at line stretch.
