Is this route of a airforce jet on flightradar faked? While looking at the flight routes of Indian airforce jets on flightradar, I have noticed that the trainee jets show a very weird flight pattern. Here's an example,



The width of this screenshot is around 20KM. I don't think a jet can take such sharp turns. If so, why are these turns so sharp? Is this data somehow been faked, or is this issue with the radar?
No, that has not been faked. 

Flightradar is updated with a low frequency (from that screenshot I'd estimate once per 10 seconds, maybe more). This is done to reduce the computational demands on both the service that sends the radar info to Flightradar, and on the Flightradar servers. 

Each dot in the track is one position update, and the website software just draws straight lines between them, which results in sharp corners. The real flight path will have a radius.
