Now the public are onto the chemtrails I've heard the government are using the military spraying at night to avoid the scrutiny. If you have a look at the trailing edges of the C17's of the RAAF you will see the nozzels just near the flap hangers to exploit the intuitive convergence. With the added use of mini nebulo units with ULV and the associated innovate critical technologies it makes the controlled droplet application more uniform making the chemtrails virtually invisible at night. After repeated attempts for some answers both ASIO and ASIS will not comment.
