Aerial firefighting is the use of aircraft and other aerial resources to combat wildfires. The types of aircraft used include fixed-wing aircraft and helicopters. Smokejumpers and rappellers are also classified as aerial firefighters, delivered to the fire by parachute from a variety of fixed-wing aircraft, or rappelling from helicopters. Chemicals used to fight fires may include water, water enhancers such as foams and gels, and specially formulated fire retardants.
Cloud seeding, a form of weather modification, is the attempt to change the amount or type of precipitation that falls from clouds, by dispersing substances into the air that serve as cloud condensation or ice nuclei, which alter the microphysical processes within the cloud. The usual intent is to increase precipitation (rain or snow), but hail and fog suppression are also widely practiced in airports.
For release by aircraft, silver iodide flares are ignited and dispersed as an aircraft flies through the inflow of a cloud. When released by devices on the ground, the fine particles are carried downwind and upwards by air currents after release.
Chaff, originally called Window by the British, and Düppel by the Second World War era German Luftwaffe (from the Berlin suburb it was first found near), is a radar countermeasure in which aircraft or other targets spread a cloud of small, thin pieces of aluminium, metallised glass fibre or plastic, which either appears as a cluster of secondary targets on radar screens or swamps the screen with multiple returns

There is nothing crazy about the American Military admitting before Congress in 1977 that indead they have tested for spread and effects of biological agents on 249 populated areas .

Although it looks very intimidating, and is certainly not good for our health, chaff is NOT the white lines in the sky that believers claim are "chemtrails".

I'm still on the fence with regards chemtrails. I have seen a few documentries on them, but they were all pro-chemtrails, so I realise they're slightly biased. However, one piece of evidence that stands out to me is the numerous toxicology reports of varying areas of water, which show extremely high levels of barium and aluminium. How can you explain a lake which has 350000 parts per billion of aluminium? This comparing to the dangerous high quoted by the government of 1000. The only source to this lake, which I believe was underground, was tested and this was found not to be polluted. There are several instances of this shown in the Edward Griffin backed documentry- I believe it's called "What in the world are they spraying?". Also, how can you explain severe changes in soil pH over the past 10 years in the same area?
Aluminium is the most abundant metal in the Earth's crust, and the third most abundant element, after oxygen and silicon. It makes up about 8% by weight of the Earth's solid surface
Also in keeping with the element's abundance, it is well tolerated by plants in soils (in which it is a major component), and to a lesser extent, by animals as a component of plant materials in the diet (which often contain traces of dust and soil). Soluble aluminium salts have some demonstrated toxicity to animals if delivered in quantity by unnatural routes, such as injection. Controversy still exists about aluminium's possible long-term toxicity to humans from larger ingested amounts.
