With so many comments concerning incompetence bordering on negligence, it is interesting that the authorities have seen fit to allow them to travel/escape back to Korea. There must be a good reason for that, right??
If one compares what the authorities would do with say a cross-border Mexican long-haul truck driver, who let's say was involved in a significant, but single vehicle accident causing the deaths of multiple pedestrians, where culpable negligence seemed likely, I doubt the truck driver would be allowed to leave pending their decision on whether to press charges in relation to the deaths.
That the US have allowed the prime suspects in the Asiana crash to leave the US, would either be indicative of pressure from for example the State Dept to prevent their detention turning into a political hot potato for the current administration, or, just possibly the NTSB investigation may not have enough evidence of culpable negligence to recommend charges being brought against the Asiana crew.
It begs the question - does being incompetent, when it results in a crash and deaths, mean that crew such as this, should be held fully accountable for their woeful lack of ability and awareness, and be subject to the appropriate legal system?
IIRC, Capt Barry Woods was interrogated for 2 days before being charged, and he was not allowed to leave Korea after the Cheju incident.
Double standards anyone?
