Hi,
I am currently using the API for a little project regarding my local airport and while working with the data, I sometimes found weird issues with airplanes jumping back and forward in time. This is also visible in the Explorer and I recorded a short video demonstrating the problem:
As you can see with the highlighted SWR176, as well as with other traffic, the position displayed jumps back to earlier positions. Initially it jumps back to the take-off run and later it jumps back several miles.
However, this issue seems to be very sporadic, so I am not sure what causes it. I had it occure during the middle of the night on previous days, as well as during daytime hours like today.
Best regards,
John
