Sorry but my Friend who retired from USAF said he supplied the planes with the spraying chemicals
for the planes. I asked him last night why they sprayed and he sent me this

To protect us and our electronics from coronal mass ejections from our sun and from plasma discharges from the core of our universe while we are above the ecliptic. Of course the metal used have their own side effects, kills many plants so new genetically engineered types of trees are being designed that survives these particulates when they rain down. At least that is what was planned years ago, when the cycle was discovered right after the last one wiped out our telegraph system in moments. https://news.nationalgeographic.com/news/2011/03/110302-solar-flares-sun-storms-earth-danger-carrington-event-science/
