huge loss for the world.
It will burning for a while unfortunately. We (vol. firefighter) had a 500 unit apt building that was under construction go up due to roof work. Hot tar, torches, etc can lead to ignition. The heavy timber that the church is built with has a much higher density than modern wood found at Home Depot. It can take longer to ignite but once ignited, it will burned for much longer.
Sad day
