Kit Oliver, an Australian fisherman, claimed that he found a section of the missing MH370 plane in October 2014.
He told 60 Minutes: "Pretty much as soon as we saw it, we thought it. Of course we did. We got a pretty fair look at it."
Jacquie Gonzales, whose husband Patrick Gomes was on the aircraft the day is disappeared said: "I thought we would have answers way, way earlier."
"He's not coming back so we have to accept it, but we still need to know exactly where he is and how it happened."
The fate of MH370 has been the subject several unfounded conspiracy theories, with some suggesting it was hijacked by Russians or that it landed at a US military base on the remote island of Diego Garcia.
Ex-Malaysian prime minister Mahathir Mohamad even proposed that the US Central Intelligence Agency knew what happened but was covering it up.
Many believe that the aircraft came down in the southern Indian Ocean.
