Transport Canada says the suspected human excrement that has landed on cars, people and property in British Columbia over the last six weeks didn't come from airplanes. About a dozen incidents in which a foul-smelling substance has fallen from the sky have been reported but Transport Canada says its investigation ruled out aircraft involvement. The department said it interviewed owners, operators and airport staff and reviewed radar tapes and found no aircraft connection to the reported incidents. "The department's review has concluded that these incidents do not meet the description of blue ice and are therefore not aviation-related," it said in a statement.
