Watching Firefighter Planes

Forest fires are burning in the immediate surroundings of Athens again. Firefighter planes drone on over our building. We went up to the terrace and watched a couple of Canadair planes, a russian Beriev, and a helicopter. There's lots of smoke and appart from the fire on Ymittos (which we can clearly locate) there is a big yellowish cloud which we don't know if it's smoke or a normal cloud.

This thing makes me angry and sad. I wonder how much it all costs. Or how much just the planes and the fuel cost. Is it really worth for some vultures who are looking to get a fast buck with some real estate?

At least it seems to me that bringing in the Beriev from Russia was a good thing after all. After the first drop by the Beriev (we can't see the actual drop from our building) the dark smoke on the Ymittos fire lessened significantly.
