My point is that he had the tools available to make sure that the body was nothing more than ash and small bone fragments, why wouldn't he do that instead of trying to deal with a charred body. Your suggestion that he would drive or fly around with charred remains, throwing body parts out of a plane doesn't make sense to me, and seems to be twisting my words. People dump the ashes of their loved ones from planes all the time, why wouldn't he do that? Even if he didn't have a valid pilot's licence (which we have seen no proof of from what I recall, so I don't know where that idea comes from), I would think flying without a licence is too small of a crime to be worried about if you just committed a murder.
My point is, if you have the proper tools to do a proper job, you would need a a very good reason not to do a proper job. Why would anyone bury a body when they have an incinerator at hand? Why would he bury the ashes and leave them all in one place when he could have scattered them to make it impossible to find them?
And back to the Harley, a real chop shop doesn't keep their wares around for 6 months, that is not how chop shops work. Which again makes me wonder if it really was a chop shop in his hanger, or if he knew about it, because again, if you have a chop shop and a stolen vehicle, you don't have a problem, you have a solution.
We read in the media that deliveries (of what we have no idea) were halted for that week, so that would eliminate the 'business as usual interrupted their ability to leave that hot truck there' theory, in my opinion. Add in the fact that apparently, they had other stolen vehicles at the hanger, so what is the difference between one stolen truck and a hanger full of stolen trucks, if you're going to get busted you're going to get busted. And if they thought that they were going to get busted, you think that they maybe would have spent the week getting rid of the other stolen parts that made it look like a chop shop, just in case. Especially, if some have suggested, you think that the police are hot on your trail.
