A workers' rights representative said on Wednesday that a coroner's inquest should be opened into the fatal collision that happened at the airport on Monday.

In the accident, an Emirates cargo plane veered off the runway before crashing into a security patrol vehicle and pushing it into the sea, killing the two guards in it.

Fay Siu, chief executive of the Association for the Rights of Industrial Accident Victims, told a Commercial Radio programme that the airline had neither reached out to the victims' families nor offered condolences.

"We believe that this case should be treated as a major incident," she said.

"The investigation report should be made public and there should be a coroner’s inquest.

"Yes, inquests can be drawn out, but there’s no way around it.

"It is the best way to gain a clear understanding of what happened and prevent similar accidents. It also provides closure for the families."

Both victims were the breadwinners in their families, Siu said, and their deaths have placed a huge financial burden on their loved ones.

She urged the government to take the case seriously and said the administration should consider confiscating the travel papers of the aircrew or temporarily bar them from departing from the SAR, as prosecutions could be difficult if they leave Hong Kong.
