Surabaya, Indonesia (CNN)Divers are preparing to investigate underwater pings that may be coming from the flight recorders of AirAsia Flight QZ8501, Indonesia's military chief said Friday. An Indonesian search vessel had earlier detected the pings, said Gen. Moeldoko, the head of Indonesia's armed forces. He was speaking on board the ship that is being used as a base for divers trying to raise the tail of the AirAsia plane, which went down in the Java Sea on December 28 with 162 people on board. But there is also caution surrounding the possible pings, because the sound could be emanating from other sources. In the case of Malaysia Airlines Flight MH370, several signals raised hopes of locating the missing plane, but proved to be false leads.
