November 26, 1966-While en route from Apia, Western Samoa to Pago Pago, Polynesian Airlines Flight 5WFAA sighted the wreckage of an overturned vessel and reported it to the Federal Aviation Agency Flight Service at Tafuna, American Samoa.

USCGC Cape Providence, moored at Pago Pago on search and rescue standby, was notified of the sighting. With an assist from the Polynesian airliner, the cutter located the disabled fishing vessel named Main Sun No.2 and found 17 survivors clinging to the overturned hull. Despite the rough seas breaking over the hull, the Cape Providence rescued 13 of the survivors, while 4 more were retrieved from the water by the fishing vessel Chie Hong No.20, which had arrived on scene to assist. Two members of the 19 man crew, however, had been trapped in the engine room on the capsized vessel and had perished.
