Whatever thier sources are, I think the chances of losing comms, radar contact, having a total transponder failure AND THEN actually
having a mid-air collision must be extremly low. Maybe thats what they are getting at?
I made the post to highlight the growing concern of how the Brazilian Air Force are handling the investigation.

Embraer Asked to Provide Records for Legacy Aircraft
Airline Industry Information
Brazil's aircraft maker Embraer has been asked by the country's federal police to provide records of test flights and the flight data recorder for an executive jet that collided with a Boeing 737.
According to a federal police press officer, investigator Renato Sayao wants to examine the records of the four test flights and three acceptance flights, The Associated Press reported.
The Legacy aircraft was on its maiden flight to purchaser ExcelAire Service Inc in the United States when it collided mid-air with GOL Flight 1907 on 29 September. All the 154 people on board the GOL flight were killed while the Legacy landed safely at an air force base.
Embraer Testing Department director Mauro Costa told police that the seven test flights occurred without incident and that there was no failure in the transponder that provides the aircraft's location or in the TCAS anti-collision system.
It has been reported that early analysis of the flight data recorders indicated that the Legacy's transponder was not providing its location at the time of the accident.
