MH370 Tomorrow will be the second anniversary of the missing Flight MH370 and Bukit Mertajam MP Steven Sim said there were still many unanswered questions, even with over 20 countries involved in the search over the last two years.

Sim in a statement today said the questions revolved around matters of national security as well as deep concern for families of the victims.

At the same time, he also claimed that the BN federal government had refused to answer any questions raised on the missing Boeing-777, both in and outside of Parliament.

Among others, Sim said his parliamentary question in June 2014 on the subject of military negligence for not taking action despite detecting MH370 on a rogue path, was rejected on the pretext of it being a “secret”.

"I have repeatedly called for a parliamentary select committee on this issue with the view to publishing a white paper on this landmark aviation crisis affecting not just Malaysia and Malaysians but which also has global implications.

"I have also called for the publication of the results by all authorities involved in the investigation - including the Department of Civil Aviation, the military, the police as well as the Joint Investigation Team," he said in pointing out that so far there has only been one Interim Report published one year after the incident.

"Especially of concern is the police investigation notably on pilot captain Zahrie Shah, given that he had been seen on numerous occasions as 'chief suspect' by the police.

"The government must provide clear answers to these serious allegations so as to clear the name of the pilot and his family if he was innocent," Sim said.

Shortcomings and weaknesses

Sim also noted that the 584-page document released last year had recorded shortcomings, non-compliance and weaknesses in Malaysia Airlines, Malaysia's aviation authority as well as the military.

"There was even a breach of international protocol under the terms stipulated by the Operational Letter of Agreement between the Department of Civil Aviation Malaysia and Vietnam Air Traffic Management.

"One year has passed since the Interim Report; what has happened to the various issues of non-compliance and negligence highlighted? No one can tell, even after our repeated questioning," he said, adding that the incident could potentially recur unless steps were taken to answer the questions raised.

Beijing-bound Flight MH370 went missing roughly an hour after leaving Kuala Lumpur two years ago.

There were 227 passengers and 12 crew members on board.
