A "don't leave the country" restriction is pretty common for people under criminal investigation. Their final status will be determined by a court of law, and I'm sure your pilots will be cleared and allowed to leave the country.
And, at this point of the investigation, I think it's pretty obvious that 2 people should be released without delay.
And, to be honest, considering the way the Brazilian authorities have been handling this matter so far, I wouldn't trust any of them to fry an egg much less investigate this accident properly.
