M Mouse,
Sorry but my post was written entirely by me. Not by the source you claim. I have the full details of the incident. There was no un-commanded thrust reduction or engine shut down but the loss of the inboard and mid LE slats was enough to cause the stick shaker at 12 feet and a level off at about 40 feet.
Extremely scary stuff in a heavy 744 out of JNB.
Still, very well handled by the crew involved.
