Actually there's a lot of threads out there that are throwing out arson,terrorists etc. The French inspectors/fire dept etc better make sure they nail the investigations because there's been what 10 church fires in France alone these past few weeks.I don't think there was ever a thought of it being intentionally set or through nefarious reasons. Minus in this thread of course...
On 13th century midieval buildings in a congested urban center?
Fixed wing or rotary?Yes.

The original conversation was regarding water bombers, which was pointed out as being impracticable.Rotory
But helicopters can do.The original conversation was regarding water bombers, which was pointed out as being impracticable.
In an urban environment, it is virtually impossible for a fixed wing to make a pin-point drop on a single structure and even then, the volume may cause damage.
The only time I have seen fixed wing bombers make drops on structures, is when they were trying to create a line and the structures targeted were already involved and beyond saving.
Matter of fact, I saw way too much of that just this last year...
Surely....can be done.I'm fully aware of what helos can do.
But they are rarely used on urban structures. I posted a photo in post #32 of one making a drop on a building in Los Angeles, but that was a rare and isolated instance.
So it is possible but not practical in a metro/urban setting.
Again...see post #32Surely....can be done.
This report was also on the evening news, i.e., that there was an initial alarm with no fire found and by the time of the second alarm the fire was already far advanced. Be interesting if accurate. If there was this initial alarm it would be very informative to know what type of detector alarmed. Smoldering fires and burning fires produce different types of particulates. In general ionization smoke alarms are best for detecting rapid flame fires while photoelectric smoke alarms protect against slower, smoldering fires. Often times malfunctioning detectors give several false alarms and responders tend to treat them as "the boy who cried wolf". One can only speculate on how different the outcome if that initial alarm had been located or responders remained on the scene a few minutes longer.There are now reports that a fire alarm went off, but they couldn't find a fire, then later another fire alarm went off but when they found the fire it was already too far gone to extinguish. If they are anything like the fire sensors in my house you don't need a flame or smoke, hot air sets them off.
The fire alarms in my house have sounded off at me soldering in the bathroom, making toast, grilling cheese, and opening the oven door. One upstairs one downstairs they are not in a room but outside all rooms. In the roof of a cathedral which is all old dry wood if you have a proper fire it is probably too late to put it out without an automatic sprinkler system.This report was also on the evening news, i.e., that there was an initial alarm with no fire found and by the time of the second alarm the fire was already far advanced.

Generally speaking rapid-rise and/or fixed temp fire alarms are only employed in non-life-safety installations where the environment has too many airborne particulates due to excessive steam, moisture, dust, humidity or temperature, such as in attics, and garages. They tend to be tricky as the area may be subject to rapid temperature rises or high temperatures in the normal course of events like summer heating
It'll be rebuilt.
Several churches and cathedrals that were destroyed in WWII have been rebuilt like Monte Casino, Konigsberg cathedral, St, Gervais church and the cathedral at Cologne.
I think Macron thought a national campaign to contribute and rebuild it as a nation was a good idea but was undermined by a few individuals throwing in a few hundred million of their loose change.Problem is not the building, but that art that is destroyed. I believe that the building will be restored, but those art pieces will never come back.
Having said that, it is a bit strange to me that within a few days, almost a billion euro's is been raised to restore the building, while many projects to aid other people are struggling to get some money. Clearly an old building is worth more than a milion human beings.
