A Gol airlines jet with 140 people aboard was missing Friday in the Brazilian Amazon, Brazilian aviation authorities said.
Brazilian airport authority Infraero President Jose Carlos Pereira said the air force was searching for the jet in a densely forested region.
The plane left the Amazon city of Manaus on Friday afternoon, the O Globo news agency reported, citing aviation authorities.
The Gol jet reportedly struck a Brazilian-made Legacy aircraft near the Serra de Caximbo region in Para state. The Legacy managed to land in Serra da Caximbo.
Pereira said in a radio interview to CBN that a local farmer reported seeing a large plane flying low.
