Why did the 9/11 'falling man' image disappear?

At Design Observer, a fascinating piece on how photographer Richard Drew's iconic, disturbing image of a man falling to his death from the World Trade Center on 911 has been erased from public view.

It's an interview with Henry Singer, who in 2006 produced and directed The Falling Man, a 90 minute documentary for UK's Channel 4.

A snip from Singer's comments in the Design Observer interview:

What is extraordinary beyond the graphic composition of this image — the parallel lines, the light on one of the towers — is the fact that the Falling Man, as he has come to be known, looks so composed. It’s the most horrific moment but there is a calmness to the image. And I think this is one of the reasons why it is so memorable. It captures the last moments of somebody’s life but it does so in a way that is peaceful and beautiful at the same time. That is one of the many reasons why it has burned itself into the consciousness of anybody who has looked at it.
