(thinks: Do Brazilian pilots have to follow different rules when they leave Brazilian airspace? Are the rules that different?)
Excellent point barit1, if in fact true, the posters here that are blaming the Legacy pilots for the accident for
not changing their FL without ATC approval are proved totally wrong or Brazilians pilot would have been being violated by every country in the world.
Of course they are not, because Brazilian pilots are very professional.
(The real one's anyway.)
