Ärende: WWII revisited
======================
Okay... I finally learned something from you... and Dan Ceppa who stated about
hydrogen not being able to be the cause of the fireball shown as hydrogen burns
colorless.

I'm not an expert in those fields, nor even slightly knowledgable in it.  I
could only go on "naked eye" observation.

That wasn't painful, but don't let it go to your head... and thank you for
dispensing with the heat of the other thread on that.

 RW>>> So, where did the fire start?
