Please, for your own life and your future well being, do not EVER approach an airplane crash from downwind without a proper respirator.

The composite materials that make up a great bit of a lot of airframes are very dangerous. The epoxy binder is very bad on its own when it burns, but the fibrous material of the composite itself can easily be wafted up into the air by the heat & carried along with the smoke.

These fibers can end up in your lungs. Imagine thousands of tiny bits of glass/carbon fibers becoming permanently stuck in the inner linings of your lungs. This leads to inflammation of the lung tissues, causing you to slowly suffocate. In instances when it is not fatal, it leads to permanent scarring of the lung walls and BAM you were a nice healthy 19 year old, now you are a 19 year old with chronic pulmonary fibrosis and possible lung cancer.

The video is not worth it.. Don't get too close, please.

You can refer to this paper from the FAA

Here is a little exceprt from Mayo Clinic about Pulmonary fibrosis: Pulmonary fibrosis occurs when lung tissue becomes damaged and scarred. This thickened, stiff tissue makes it more difficult for your lungs to work properly. As pulmonary fibrosis worsens, you become progressively more short of breath.

Imgine knowing that the next breath you take, no matter how hard you try, will always be a little shorter than the one you just took. fucking scary man.
