601 et al
Some of the fires inthe West Coast of Calfornia and a lot around the Med are Eucalypts. Using large aircraft seems to be considered the norm there. Try and drag up video of the Canadairs fighting the resulting scrub fire in Greece after the Helios crash. They sure look like Eucalypts to me. Hence my comments about bathwater etc.
I've watched from nearby large firebombers in action in LA with Eucalypts burning and yes the fire was extinguished with the help of Trackers, a DC6 and a couple of Orions.
