 I am having trouble imagining any scenario where you would have a line

 Brent,
    Thanks for the picture.  Gives some perspective.
    I've also read about "controlled" emergency landings that result in
partial destruction of the airplane with fire ensuing.  I don't have the data
on the fire source.
