Its not just that one passpprt that survived the crash (it was picked up before the collapses).
For example... Luggage, a airline itineray, a letter from a passenger and a crap load of other perishable stuff you'd find in a plane all ejected from it. You'd have to imagine little ninjas running around planting the stuff in broad daylight.
And I gave you a link to another time a perishable item survived a plane crash.
You are quite right...it was picked up before the collapse, I am sorry for that. Look I said it before, we'll just have to agree to disagree, this is a total non issue.
