Only time I got interdicted was seconds before I was about to drop out at the station, so I just aimed my nose straight at the planet and crashed right into the atmosphere, and the NPC on my tail vanished. one quick FSD cooldown later and I was at the anchorage safe and sound.
Been interdicted twice in eight cargo-laden arrivals at Stuemeae FG-Y d7561.
Also had to fire off a heatsink on two occasions when my arrival in-system placed me between the two stars.
