A transportation vessel that is doomed, but will keep you safe upon impact. The U.S. Airways flight that belly flopped into the Hudson River was Cactus 1549.
Friend 1: "Man, I don't want to ride in your car. If you go faster than 60 mph, it starts shaking like an addict and smoking like Lindsey Lohan."

Friend 2: "No way man. That thing is a Cactus 15-49. The only time you've ever been safer was when you were in your mother's womb."
