near miss: airplane versus terrain

I recently ran across this video on the wildland fire hotlist forums.

Some terminology:

VFR refers to visual flight rules.
IMC: instrument meteorological conditions (i.e. I can not see).
IFR: instrument flight rules, flying with instruments when you can not see.
scud running: flying in VFR conditions or under the clouds to avoid IMC conditions.

Here is a Dept. of Interior "Lessons Learned" Aviation safety advisory on inadvertent flight into instrument meteorological conditions.
