That said, insurance companies aren't stupid. Would they really let the person insure the plane for so much that it is better to lose it for insurance than to simply sell it?
Not at all. GA aircraft have slow stall speeds, and as you can see from both scenarios, first-responder response time is extremely quick when you follow protocol. The Cirrus even has an airframe parachute for a soft landing.
Not for nothing, but Vso (stall speed with full flaps) in the CIrrus SR22 is still 59 knots (68mph/109kmh) and remember airframes don't have the same crash safety features that automobiles do. It's a lot slower than an airliner's would be but you're not exactly gently touching down.
Ray Clamback, one of the more experienced ferry pilots (300 US->AU deliveries from memory) went into the drink off Hawaii on two separate occasions and had to tread water for 10 and 6 hours respectively. Nothing "safe" about it.
I never understood why they don't just strap them on a ship and send them out as project cargo. Or take the wings off and containerize. That's done all the time for Yachts which are perfectly able to be sailed to destination. Only real difference is how long it takes but a modern container liner is suprisingly fast.
For example, to ship a new Cirrus SR20 to Australia starts at $28,995 and you'll need to wait for factory reassembly and certification. To ferry the same aircraft costs $22,800.
there was a member of Microsoft Pilots that did exactly that. Faked a crash on land as prep, crashed in Elliot Bay and swam to the house of his ex and "stole" a car in an attempt and insurance fraud.
