Numerous Australians have shared their 9/11 Stories with ABC News Online, but Penny's stood out, for its vivid detail and images of the unimaginable horrors witnessed by so many survivors that day, from all over the world. One of Penny's photos, taken from her hotel room, close to the World Trade Centre complex on the morning of September 11, 2001, shows the aftermath of a man who jumped from the burning skyscrapers :

"There is a dead man about the middle of (this shot of the courtyard below my hotel).

"He's wearing a pink shirt and white pants. I've often wondered if I could somehow track down his family, who would likely know what their husband/father was wearing and whether it would give them any comfort to know exactly what happened to him and that he didn't die alone because I watched and prayed and cried as he died."

The reflections falling across the WTC plaza, in Penny's photo, are from the windows of the World Trade Centre 1 and 2 towers. Within 40 minutes of the photo being taken, both towers will have collapsed, consuming, swallowing up the remains of this unknown man and some 200 more people believed to have leapt or fallen to their deaths.

The fall from the upper floors of the WTC towers would have lasted 9 to 10 seconds.
