Did they find any parts (human remains) of the people onboard the 9/11 planes ever?

There were no body parts because there were no planes. All evidence for planes crashing on 911 has turned out to be planted or fake.

Yep, I know that, but if the people who believe the "story" dont know that, then where was their proof?

This is only one link to get you started. Google can be your friend. However, I sure this will not be good enough, because you already have your own answer.

Never mind the numerous articles on thee NYC medical examiner doning DNA tests on found bocy parts. Only cause he works for the goverment (NYC goverment) and is part of the coverup.

Thanks, but I meant of the supposed passengers of the supposed planes.
