This seems very similar to the most recent aerial platforms acquired by BSPP, joining the earlier acquisitions built by Metz on Scania chassis.
Six platforms were deployed at the recent Notre Dame fire, along with eleven exterior and interior hand lines and ground monitors, as well as one inside the building on a remote controlled tracked robotic device.
Water was supplied both from hydrants on the island and both banks of the Seine, as well as by fire boats relaying through several 110mm hose lines up the steps next to the adjacent bridges.
Fortunately, the pre-plan had been practiced as recently as last September. The focus was to remove irreplaceable artifacts first, then focus on the roof fire, and this was executed very well. Losses seem to have been minimal, although some items were inevitably damaged.
The two main problems were the rush hour traffic and the enormous crowds, both of which seriously impeded access for the firefighters and slowed down every phase of the intervention.
There was also an enormous police presence, but it is not clear if this helped or merely added to the congestion and made the operations more difficult...
