based on my own personal experience: 2nd post, the first did not get through for some strange reason.
there is a user in olbia that when he turns on his rb, "captures" some aircraft from positions seen by me normally without network turned on, it seems that the network has precedence over "my flights", so i see less on my flights and more network flights in marginal areas that overlap as direct reception zones. i don't know if the same happens to him when i am on
