brazil needs to decide wether it's signed up to the ICAO rules on accident investigation or not. (annex 13). Its scandalous that they are trying to pin the accident on someone before the investigtion is complete. Also trying to pin it on the only 'someone' involved that wasn't brazilian. (mind you a certain european country close to our own shores seems to go in for that occasionaly!).
I think the answer though for the pilots involved is easy. Don't go back to brazil, and for the american authorities to refuse to extradite them as its patently obvious that they are not going to get a fair trial.
