Well, it took me about the same amount of time to determine that proper claim to identifying that supposed life vest as having anything at all to do with 9/11 cannot be made.
That photo comes from a source, that by its own claim, had the following as and for its purpose:
"The objectives of the work described in this paper were two-fold: (1) to
collect information about the structural and nonstructural damage suffered by
the building at 130 Liberty Plaza due to the collapse of tower 2, and (2) to
investigate whether simple numerical tools used in the structural analysis of
buildings can be used to help explain the observed structural behavior. The
first objective was achieved by the September 23 walk-through of the
building. Summary information on the building damage is presented in the
reconnaissance section. The second objective was addressed using linear and
nonlinear analysis tools that are used by earthquake engineers. Berman et al.
(2002) and Warn et al. (forthcoming) present detailed information on the
September 23 reconnaissance and the subsequent studies."

This is typical of debunker shenanigans. Always seeking to use bogus sources to make unsubstantiated claims. That study does not have any way of substantiating the claim the lifevest comes from Flight 11 -- remember, as well, that this is a thread dealing, not with American Flight 11, but with United 175. So, at the outset, the AA lifevest is a stupid derail in any event.
The people conducting the study were not collecting or documenting evidence and had no authority to do so; nor does it appear they even attempted any such investigation. The photo is a throw in, an after thought, as it were. They were studying the damage done to 130 Liberty Street.
That is not how research is conducted; instead, that is how propaganda is engaged in.
Please cut the crap and check your sources for validity and for reliability before subjecting yourself to easy refutation.
Furthermore, even as to its stated purpose, the exercise the writers of that study engaged in was obviously fubar.
130 Liberty Street is being dismantled, apparently on a stick by stick, stone by stone, beam by beam basis because it has mold.
It still hasn't been removed to this very day, nearly nine years later. SAIC still has the building shrouded in secrecy, covered, hidden and obscured.
Needless to say, all of that special handling and secrecy almost certainly has nothing at all to do with simple mold. That building was compromised by DEW and that is why it is being handled so ginerly and oh so slowly.
The study may prove useful because as of the date it was initiated, 9/21/01, it described the damage to the building in simple terms, giving no hiint at all that nine years later the building would be shrouded in secrecy and mystery, still standing. In the interim, it has caused mysterious death and has had inexplicable fires and has been both repaired and then declared unfit and then declared nearly impossible to demolish, absent the most special care imaginable.
Your study does not foretell anything of what was to come.
Thanks for posting that article. Some good use may come of it.
Meanwhile, as to your lifevest claim, do better.
sheesh
