Helicopter story and the sadness of Brian Williams (1)

Recently anchorman Brian Williams has been exposed as having lied about an incident in the Iraq War. For years he had claimed to have been in a helicopter which was forced down after sustaining damage by Iraqi army fire. In fact, he was riding in a later helicopter, and viewed the damaged helicopter and spoke to its pilots when he landed. I do not know whether Williams really lost track of what really happened, mistaking media imagery for his own memory (though I sometimes find myself wondering whether a mental image is a direct sedimentation of personal experience, or a picture I saw of it), or deliberately lied about it.
