Manyak and his two crewmates, from their small fishing boat in the northern Malacca Strait, saw a low-flying plane which was issuing black smoke, on Saturday 08 March 2014 WIB.

Selasa, 18 Maret 2014.
Dua nelayan Gampong (desa) Ulee Rubek, Kecamatan Seunuddon, Aceh Utara, Irham Manyak (40) dan Muhammad Adam mengaku melihat pesawat terbang jatuh yang diperkirakan di sekitar perairan Kota Langsa.
Mereka mengaku menyaksikan pesawat yang saat itu berada di ketinggian sekitar 200 meter tiba-tiba mengeluarkan asap lalu menghilang.
Jatuhnya pesawat itu bersamaan dengan hilangnya pesawat Malaysia Airlines (MAS) dengan nomor penerbangan MH370 tak lama setelah lepas landas dari Bandara Kuala Lumpur, Malaysia, menuju Beijing, China.
Irham Manyak kepada Analisa, Selasa (18/3) mengatakan, pada Sabtu (8/3) itu dia dan Adam tengah mencari ikan di laut. Mereka melaut sekitar 30 mil dengan menggunakan perahu tempel. Tiba-tiba, akunya, mereka melihat pesawat berwarna putih mengeluarkan asap dan sekitar lima menit kemudian pesawat itu menghilang.
“Namun kami tidak tahu apa jenis dan tulisan di badan pesawat tersebut tidak terlihat karena berkabut,” ujar Irham.
Panglima Laot Seunuddon, Amir Yusuf, mengatakan, kedua nelayan tersebut saat itu sedang memancing di perairan Aceh Timur. “Pesawat itu jatuh siang hari. Lokasinya tak jauh dari tempat mereka memancing.
Mereka yakin bahwa yang jatuh itu adalah pesawat terbang, bukan benda lain,” ujarnya mengutip pernyataan nelayan tersebut.

Seunuddon Fishermen Report Seeing Falling Aircraft.
Tuesday, March 18, 2014.
Two Gampong (village) fishermen in Ulee Rubek, Seunuddon Subdistrict, North Aceh, Irham Manyak (40) and Muhammad Adam, claim to have seen a falling plane, estimated to be in the waters off Langsa.
They said they saw the plane, which was at an altitude of about 200 meters, suddenly issue smoke, then disappear.
The crash of the plane coincided with the disappearance of the Malaysia Airlines (MAS) plane with flight number MH370 shortly after taking off from Kuala Lumpur Airport, Malaysia, to Beijing, China.
Irham Manyak told Analysis on Tuesday (18/3) that on Saturday (8/3) he and Adam were looking for fish in the sea. They travelled for about 30 miles in an outboard boat. Suddenly, he said, they saw a white plane emitting smoke, and about five minutes later the plane disappeared.
"But we did not know what type, and the writing on the fuselage was not visible because it was foggy," Irham said.
The Sea Commander of Seunuddon, Amir Yusuf, said that the two fishermen were fishing in the waters off East Aceh. "The plane crashed during the day. The location is not far from where they were fishing. They are certain that the object which crashed was an airplane, not something else", he quoted the fishermen as saying.
