I think the analogy might best be put at the borderline between flying-chicken-man and the Sopwith. Obviously there are some folks that are flying, and flying reliably, obviously some things work and some things don't -- so now is the time to start writing it all down and sorting it out.
The problem is that we can't even see the airplanes of the folks who are flying -- we just get to hear the cool stories about how they got from point A to point B.
I look at places like DreamWorks which are able to capture "lightning in a bottle" over and over again or some of the serial entrepreneurs out there, and think that it is possible to take highly variable environments and put a little bit of structure around them. Nowhere near as much as aviation, but like the other posters pointed out, the only reason we have that for aviation is that a lot of smoldering craters became somebody else's life lesson.
Not only is the problem space nearly infinite in comparison to flight, but the "physics" governing business success change impossibly fast.
None of that is to say that we shouldn't study failures, but the question is which failures have widely applicable lessons? If you indulge me to abuse the analogy further, most startups are like those early flight attempts by people who jumped from high places wearing ridiculous balsa and fabric contraptions.
