"Your front-end is constantly updating the position of the other planes you can see based on the data sent to you from the host."

The rate your front-end recieves updates on other planes is determined by how far away an individual plane is from you. At the range inside of 2000 yards, you will recieve the most frequent updates on a plane. Because of this, another players unsatisfactory connection to the host may not become appearent to you until you close within that range.
One common scenario players find is that they see a distant enemy plane flying on a steady course. If that enemy plane has a shoddy connection, it will not show when they are not maneuvering. As the player closes in to attack, the enemy reacts to the attack and starts maneuvering. Also at this time, the attacker is within range for the most frequent updates. Suddenly due to the combination of these factors, the enemey plane begins to warp. This is often interpreted by players as intentional warping. In fact the enemey player in many cases are not even aware they have a problem connection, and are doing nothing to intentional to cause it. What has happened is that the combination of the enemey initiating hard maneuvers, along with the need for frequent positional updates for smooth display at close range, had caused their poor connection to become appearent all at once
