From Jambone's Link:
"...saying Captain Marwoto's negligence was not "legally and convincingly" proven."
I guess 21 victims and a hull loss don't count as "legally and convincingly proven" then. So, dear Court, enlighten me what is required for a "legal and convincing proof" ??
In addition, IMHO 2 years of jail would certainly not have helped in this case. I fear he'll be sitting in front again sooner or later putting passengers lives at risk. Has he learned from his accident ? Given his idea about wanting to fly again I guess he hasn't learned a bit. And that's what makes it dangerous...
OTOH I assume Garuda has become a lot safer now that he's not working there anymore...
