Speaking of jets on grass, I'm reminded of the Gulfstream II forced landing on grass at Mallow, Eire. I flew over the place in the 80's, and was curious what a beautiful 3,000 foot tarmac runway was doing in the middle of nowhere.
It's a lovely story, now made into a film... but d'Irish tell it better than I could...
