This is clearly a major safety issue if any non essential electrical component can overwhelm ship controls.
It has to be something different.
Speaking of this ship was made by Hyundai Heavy Industries, how come no one anywhere is talking shit about Hyundai and what very well could have been a manufacturing/design failure, while we get national news every time a 25 year old Boeing aircraft has a flat tire.
Should also be talking about the shit regulations that allow these massive ships to only have one source of electrical power, steering, and thrust. A 30 second black out would never be allowed on any aircraft, modern aircraft can transfer buses without even making the lights flicker (and do at least 4 times every flight).
