Some logistics
The chemtrail community assumes that some systematic clandestine operation is going on, spraying large areas of the USA (and other countries) with some kind of chemicals.
I thought it would be interesting to figure out the logistics of such an operation (I will later make this available as a spreadsheet):
Let us assume that an area of 2000 by 3000 km is to be covered (this roughly corresponds to the size of the United States). (1 mile ~ 1.5 km) Let us further assume that spraying is done in parallel strokes 3 km apart. On average, one spraying per week is performed (some areas more, some less), and a plane is in the air 20 hours a day, leaving 4 hours for refueling, reloading and maintanance. Two crews of 3 take turns flying the plane, spending 10 hours a day flying. For each plane, there is a ground crew of 7, including maintenance personnel, supply personnel, traffic control and planning, supply purchasing and logistics, and management. Now we can start to calulate:
The grid flown, adding 20% overhead for flying to and from the operational area, relocation of planes, etc. amounts to:
124,800,000 kilometers flown per annum.
Assuming a cruise speed of 900km/h, this requires:
138.667 flying hours.
Each plane flies 20 hours a day, so allowing for holidays, downtime due to weather and major maintenance, we assume 200 active days per year. So the operation requires a fleet of:
35 planes.
And the manpower:
451 persons.
Fuel consumption:
1.664.000 tons.
Rather a big operation

. I wonder how they keep it secret?
