I get the gut feeling he ran into bad weather and died. I know that's morbid and bad, but I think that's what happen. I honestly hope I am wrong.
I didn't note any discussion of bad weather, but perhaps I missed that.
But you know when a plane is going down it's not like it's going down at a gentle walk, it's going down fast and hard and that doesn't mean you're gonna live.
I'm not sure I agree. A controlled landing, even in rough country, is more often survivable than not. More folks survive off-airport lands than die. I've spoken to many such survivors. Moreover, an aircraft like a Citabria with a conventional gear (tailwheel) and low stall speed would be optimum for such a landing. Steve is also an accomplished pilot with a lot of experience, furthering the odds in his favor.
OTOH, it is certified for aerobatics and stuff happens. <shrug>
In any case, I suspect we'll find out soon enough.
