Authorities in Brazil have recovered 117 bodies from the crash of a Boeing 737 on September 29 that killed 154 people.

On Sunday, authorities said soldiers would continue to search the Amazon jungle for the remains of the other passengers.

The Gol Airlines flight crashed after it collided in midair with a corporate jet. The smaller airplane made a safe emergency landing, but the airliner crashed into a remote jungle, killing all onboard.

Brazilian authorities have said the American pilots of the business jet must remain in the country while the investigation continues.

Brazilian air traffic controllers said that the Embraer Legacy jet was not flying at its assigned altitude when it hit the airliner. They said equipment on the smaller plane, which would have reported its altitude to controllers, was not operating at the time of the accident.
