Click bait, hate to say it. This new clue is no clue at all.
What? You mean that finding a particle of metal such as was used to make Boeing aircraft, aboard a Boeing aircraft, isn’t a unique identifier of the skyjacker? I’m crushed. I thought the mystery was solved after all these years.
agree-click bait-even if the tie has a particle on it, it does not mean that the person wearing it was at the site-particles can be transmitted by someone touching you or bumping into you
