Not that it should make you feel better but that seems like standard operation for the pilots of the passenger "bush" planes flown all over South American countries. I have been on a number of flight like that (costa rica, Nicaragua, etc.) where even a jackass like myself who who raise his arms and let out a yell like a roller coaster ride during airplane rides like that still wants to cry like a little kid when a treetop slaps a wing strut on the way out after using up every inch of the potholed hillbilly drag strips they use to take off and land. I just give the pilots the benefit of the doubt that they are good at flying to the edge of the aircrafts abilities and not their own. Being drunk helps- ask for a flask for christmas and travel with it next time.
