The first review of the film, in German:
No clear-cut conclusion here either. It seems to me that this film just muddies the waters.
The DVD is planned to be released this month.
So as mentioned earlier, they found a small amount of barium, but not aluminium.
A PC6 [plane] from a private skydiving company is then flown into the clouds. The machine is equipped with measuring instruments which are intended to measure the barium and aluminum content of the air at an altitude of eight kilometers. A first flight brings certainty, discovering a barium level 10 times higher than the blank value. Barium should not occur at this level. Aluminium, however, was not found. Such a financially costly flight has never before been carried out and documented. So, you get to see a world premiere here. This turns the issue of chemtrails from a conspiracy theory into a serious issue that needs to be investigated. Because, as I said, there are no studies on this. The only Swiss study available for barium in the environment is that of the National Air Pollution Monitoring Network (NABEL), which studied the fine particle load in Switzerland examined 10 year intervals, but at ground level. Here, barium was found, with an increase in urban centres, but this is, for example, due to the abrasion of brakes, according to the experimenters. Had it been chemtrails, there would not be these differences between town and country.
