Air defence re-established contact with Rust's plane several times but confusion followed all of these events. The PVO system had shortly before been divided into several districts, which simplified management but created additional overhead for tracking officers at the districts' borders. The local air regiment near Pskov was on maneuvers and, due to inexperienced pilots' tendency to forget correct IFF designator settings, local control officers assigned all traffic in the area friendly status, including Rust.[1]
