To those who notices planes flying in circles, it doesn't have to be anything sinister. Those might be planes calibrating avionics or ground/airport equipment or doing test flights after maintenance. I have agencies in the region doing both, so you can sometimes find planes doing strange patterns which are their clients.
- MrZongle2 6y agoExactly. This doesn't mean that surveillance programs aren't taking place, but.... aspiring pilots gotta practice.
- flyinghamster 6y agoPipeline and power line inspectors in helicopters also tend to have weird flight paths.
- spyspy 6y agoCommercial flights will also enter a circular holding pattern around airports if they're not allowed to land for some reason. This video is a really cool example: https://www.youtube.com/watch?v=SdfVIdsufI8 https://www.youtube.com/watch?v=SdfVIdsufI8
- nickmooney 6y agoDefinitely agree! That's why the author has explicitly filtered out patternwork by excluding "circles" that are particularly close to an airport. It doesn't mean anything is sinister, but this project is definitely aware of and disinterested in just finding student pilots beating up the pattern.
