"(As of 9 p.m., we) received and accepted an offer of help via US Naval Attache Capt. Jack Sutherland; the USG [USGS] has a Fleet Survey team," he said on his Twitter account.
Roxas said the USGS team is now heading towards the crash site of the small plane carrying Robredo and pilot Capt. Jessup Bahinting and student pilot Kshitiz Chand, a Nepalese.
Actually, Robredo’s aide Jun Abrazado was also on board of the plane but he reportedly jumped off the light plane before it crash in the sea off the Masbate City or 500 meters away from the Masbate airport.
The DOTC chief said the search and rescue operations are still ongoing at the crash site.
"Diving search resumed using compressors. They have obtained compressors from the area," Roxas said.
