Where is UP and Mr. Fusion?

I'll ask again: Is there any documentation which describes someone with a plane that went up to the altitude these planes are flying in order to take samples of what is coming out of the back of those these planes of interest? Then, did they take those samples and run lab tests on them under controlled conditions? I'd be very interested in that documentation. I'm not talking about samples collected at ground level because I'm assuming all kinds of holes can be poked into that level of sampling.

When I see that level of sampling and testing documented (plane directly behind the contrail taking samples) I might jump back on this bandwagon. I'm with Mr. Fusion on this one.
