It would be strange if only the passport was found, but there were many other items

Michael Sheehan, a broker working on the 55th floor of 2 World Trade Center, moved to the stairwell when he realized a plane had crashed into 1 World Trade Center. By the time he reached the 25th floor, he could smell the fumes of fuel that had begun to filter through the ventilation systems of the two buildings.
On the street, standing in a shower of office paper and the siding from the building, he found a piece of paper. It was an airliner’s itinerary, listing information about a flight from Boston to Los Angeles.
“I realized then that it was a commercial flight. Then the second plane hit. I realized then it was terror.”

Mr. RICHARD MARX (FBI Special Agent): It’s been good. I’ve met some of the finest people that New York City has to offer that have worked alongside of us tirelessly, recovering small bits and pieces of people’ s lives. And we were finding basically the small fragments, whether it’s pieces of jewelry, their personal identification, things that were recovered from on top of their desks. Just recently we found a wallet of one of the passengers aboard Flight 11, so if we can give that back to a family, I think all of us did our best to do so.

On September 11 2002, one year Anniversary of the death of our son, we were informed that the Recovery team at Ground Zero have found the ATM Bank card of Waleed [Iskandar, passenger on Flight 11] and that it will be mailed to us in Northridge. When we received it, we found it in good condition.
How could a plastic card survive the fire of the terrorist attack of the Black Tuesday on the USA?
I consider it as a sign from Waleed to his parents on the first Anniversary of his loss.

A few days before the first anniversary of our daughter’s murder, we were notified that they had found a piece of her in the piles and piles of gritty rubble of the World Trade Center that had been hauled out to Staten Island. It was Lisa’s way, we believe, of telling us she wasn’t lost.
In February, the day of the Columbia tragedy, we got word they’d found her United Airlines Mileage Plus card. It was found very near where they’d found a piece of her right hip. We imagine that she used the card early on the morning of Sept. 11 to get on the plane and just stuck it in her back pocket, probably her right back pocket, instead of in her purse. They have found no other personal effects".

On Oct. 12, it arrived inside a second envelope at Mrs. Snyder’s modest white house on Main Street here, and the instant she took it out and saw it, she says, chills just went over me. It was singed and crumpled. A chunk was ripped out, giving the bottom of the envelope she had sent the look of a jagged skyline. Mrs. Snyder’s lyrical script had blurred into the scorched paper. The stamp, depicting a World War II sailor embracing a woman welcoming him home, was intact.
Along with the letter was a note: To whom it may concern. This was found floating around the street in downtown New York. I am sorry if you suffered any loss in this tragedy. Sincerely, a friend in New York!
Since then, Mrs. Snyder, a customer service representative at a grocery store, has discovered that she has one of only two pieces of mail known to have been recovered from the planes that crashed into the World Trade Center. At least one auction house has contacted her, saying she could sell the letter for tens of thousands of dollars.
