During the Abbotsford Air Show, we could see a bunch of people out on the airfield. It wasn’t obvious what they were doing but I took some shots with the longest lens I had to see if I might later work out what was going in. My friend Mark thought it might be related to the drone display that was due to take place after dark. I think he might have been right. Looking at the shots, they seem to be waving the drones around above themselves. Maybe this is part of a calibration routine or something to do with activating them and having them communicate. I don’t know. If anyone is familiar with all of this, please do let me know in the comments.
