There then followed a long 'metallic' noise before all contact ceased. The plane never arrived at its destination, nor did a thorough visual and radio search discover what had actually happened. The plane was equipped with a standard radio survival beacon, thus the radio search, however no signal was ever received (24). The following day an oil slick north of King Island was observed although no connection with Valentich's plane could be made (either way.) Former NASA-contracted research scientist, Dr Richard Haines, concluded that this metallic noise which followed the last transmission contained "36 separate bursts with fairly constant start and stop pulses bounding each one; there are no discernible patterns in time or frequency." (25).
