"Last fall, a long-time landscaper working under contract for the City of Edmonton began noticing that carefully tended flowers and trees were showing signs of severe nutrient deficiencies.
City specifications call for electrical conductivity (EC) readings no higher than "1" in local soils. When soil samples showed damaging EC readings 4.6 to 7-times higher than this maximum permissible level, Dave Dickie suspected that elevated levels of electricity-conducting metals in the soils could be leading to the plants' "chlorosis" condition.
A life-long plane spotter, Dickie also wondered if there could be a connection to events unfolding on ATC radar scopes during his regular visits to the Edmonton municipal airport's Air Traffic Control center.
Last Father's Day, Dickie and an excited group of 12 year-olds watched two KC-135s, tagged "Petro 011" and "Petro 012", flying at 34,000 and 36,000 feet south and north of Edmonton.
According to the controllers watching the scopes, both U.S. Air Force KC-135 air-refueling tankers had flown south out of Alaska. But the big Boeings were not refueling other aircraft. Instead, as Dickie, the kids and the controllers watched, the four-engine jets began making patterns over Edmonton - "circuits" the controllers called it.
The Stratotankers were working alone in "commanded airspace" from which all other aircraft were excluded. And they were leaving chemtrails. (...)"
