The photos we see are from the 1st flight of the day, so these are not the passengers that perished. Obviously the Russian pilots and crew went down in the crash. As far as the Sky Airlines cabin crew, not sure if they were on both flights.
In some respects, the human face put on this crash may do more too help solve what happened and prevent similar incidents in the future.
Yes, it is very sad, but the impact on the flying public, especially here in Indonesia can help improve safety And awareness in the near future.
