Nearly 24 hours after a Pawan Hans Ltd. Dauphin helicopter carrying five senior ONGC officials crashed near here, rescuers have recovered the Voice Data Recorder but serach is still on for one missing pilot, officials said on Sunday. A total of 16 ships -- two of Indian Navy, five of Indian Coast Guard and nine of ONGC -- and four aircraft from Navy and Coast Guard have been pressed into service since Sunday morning. INS Makar, a special hydrographic ship with side scan sonar capability is supplementing the search efforts, officials said.
