Included in the postings are pictures from a notebook - which are supposedly the handwritten notes that the pilot of one of the drug planes - which hadn't been burned - left behind in the cockpit.

The post-er claims the book contains flight plans and plane routes for each illegal drug plane along with flight coordinates of flights - and that police confiscated it and kept it as evidence but did nothing.

Someone with a knowledge of aviation who has seen the postings said the notes appear to be precise GPS coordinates and headings to fly and to land on clandestine landing strips and also for water drops, entry and departures.
