R.I.P.
From a post at AVSIM (since repeated in other forums)
I'm very sad to inform our community that Ron Freimuth has died a few weeks ago. Considering his contribution to the FS Flight dynamics knowledge, this is a cruel loss. I make the wish we will never forget what he taught us. I also hope AVSIM will announce this sad event in its news.
God rest his soul
