My immediate thought, after being alerted by a FR headline, then looking at the plume of smoke and fire, was, oh, they’ll put it out. Then it was out of control and the spire was collapsing. It seemed then that there was perhaps a propellant in use.
Same exact story and reaction to 9/11
Not that ito suggest was lit by anyone intentionally perhaps it was incompetent workers accidentally igniting the ancient wood But why did Paris not have a better more proper response? Was it impossible to do? Or did they not care enough? And why not a fire brigade stationed on the Ile?
Well, God Blessed France in so many ways. I hope the Parisians get that, but...
I am open to all possibilities at this point. Intentional, accident, lets see the evidence (assuming they don't cherry pick it to fit a narrative).
That said, the roof was made of 150 year old wood (from a 19th century replacement) and lead (which melts and runs and spreads the fire). I could see that going up really fast whether it was set intentionally or someone left a soldering iron on when they left for the day.
