Lets get back to topic.
A video covering the press conference (held at December 21) of the Mozambique Civil Aviation Authority (IACM) can be seen here
INVESTIGAÇÕES VOO TM 470 - SAPO Vídeos
According to a post at avherald.com the IACM president João Abreu did not state that the pilot had 'A CLEAR INTENTION TO CRASH THE AIRPLANE'.
He said something like 'A CLEAR INTENTION'.
Maybe someone who understands Portuguese language can spent a few minutes to see what was actually said.
I could well be the press made something different from the statement.
