The best-known intervention mission was ending the combined siege of a train and a primary school, which was done by South Moluccan terrorists. The UIM managed to kill the six captors on the train during a short but precise raid. Two hostages did not survive this. The raid was successful due to the fact that the Royal Netherlands Air Force was called in, with six F-104 Starfighter aircraft making very low flypast manoeuvres in full afterburn. This was mainly a distraction, allowing for a swift raid and the killing of the six captors on board. The siege at the primary school ended not long after the train siege had ended.
