KAL Penang

[gas path]

Anybody out there got any idea what happened to the KAL 747-200 freighter thats got a big hole in it. Apparently spotted by ATC before it landed. Now covered with a (large!!) tarpaulin. I've seen the picture but can't quite make it out.
cheers!

This week's Flight has an article on KAL detailing this incident as being caused by a detached section of trailing edge flap.
