A Royal Thai Armed Forces search team Friday found the wreckage of a helicopter that crashed in a jungle in the northern part of the country on Thursday, killing all four men aboard, DPA reported. Third Army chief Lt. General Saplang Kalanamitr said bad weather had forced the helicopter down in the Wiang Kosai National Park of Phrae province. The search effort was hampered early on by inclement weather, but a rescue helicopter managed to locate the site using GPS coordinates Friday afternoon. The army had sent out 500 soldiers and volunteers to search the area on foot. The victims included the northern border task-force commander, Major-General Phairet Thongchaksu, 58, his aide, and both crew members.
