When I first started looking at 'Coupes, that header tank worried me some
-- 
the post-crash fire statistics for any plane with similar tank placement
is 
not so good.

So...I asked my very wise AP about it.  His response, "Well, there's an
easy 
fix -- don't crash."  But seriously, he went on to point out that lots
more 
GA pilots are killed by fuel exhaustion than fire.  A pretty good point, I

think.
