East Java sightings week
For about a week in September 1964, unidentified objects were reported over Surabaya, Malang and Bangkalan in East Java, reportedly seen by eye and on radar.

The account
Later Indonesian accounts, drawing on Jacob Salatun, say the military fired anti-aircraft guns at the objects without effect. The episode (dated 18–24 September 1964 in Indonesian press retellings) is the best-known Indonesian UFO 'flap' of the Sukarno era.
The sceptical view
The anti-aircraft detail is reported second-hand and no official file has been published; 1964 was also a tense period of confrontation with Malaysia, with many military aircraft in the air.
