A post in Geoengineeringwatch claims that C 130 aircraft are being used to spray aluminum and barium for some purpose. As evidence, it posts a photo of C130's flying, and a photo taken later of mysterious filaments clinging to power or phone lines. This is a typical example of the post hoc, ergo propter hoc fallacy. C130 aircraft are turboprops with a maximum elevation of 28,000 feet, according to Wikipedia. The geoengineeringwatch post acknowledges that these aircraft are not doing solar radiation management.
