Reply #31: The tips did shear off

The fuel laden 1/3rd of the wing had a substantial amount of (mass combined with velocity =) momentum, and punched through the facade...nothing folded back.

Oh and "reinforced concrete" ususally refers to concrete with embedded rebar. That is not what the facade of the Pentagon consited of.

The Hijacker's ID would have been in the cockpit...in front of all of the fuel, and is relatively light, open it could act like a wing. A large fuel fireball causes a wall of hot air to expand in front of it, which could have, along with the fact that the passport was already moing at high speed with the aircraft's velocity could mean it was ejected from the WTC along with other aircraft parts and hence did not immolate in the inferno.
