MH370 The biggest user of the Boeing 777, Emirates Airlines, has urged Malaysia to come clean on MH370, saying that it takes an expert to seize control of the huge passenger aircraft.

According to Aviation Weekly , Emirates Airline president Tim Clark said the theory that the plane made a turnaround flying past Malaysia undetected by radar was unbelievable and added to that, the far-fetched notion that somebody on board could have made the plane completely untraceable.

“This aircraft was disabled in three primary systems. To be able to disable those requires a knowledge of the system which even our pilots in Emirates don’t know how to do. Somebody got on board and knew exactly what they were up to,” Clark was quoted in an interview by Aviation Weekly ’s Jens Flottau.

“Something is not right here and we need to get to the bottom of it.”

Speaking after an on the sidelines of the International Air Transport Association’s (IATA) annual general assembly in Doha, Clark said that he also could not fathom where the industry’s flight tracking initiatives lacked.

To Clark, tracking is not the main issue, the magazine reported.

“We have never lost an aeroplane in 50 years, we have always known where they are. Whoever was clever enough to interdict the system, will be able to interdict this one as well,” Clark said.

“The first thing you need to do is do not allow anybody on board to disable ACARS - job done,” he added.

The Beijing-bound Boeing 777-200ER aircraft went missing not long after taking off from KL International Airport (KLIA) in the early hours of March 8, with 12 crew members and 227 passengers onboard.

Using satellite data from British firm Inmarsat, a team of expert investigators pinned down that the plane made a turn around and headed south, before disappearing over the south Indian Ocean, off Perth Australia.

This has prompted a near two-month long, multi-nation underwater and surface search. But no trace or debris from MH370 has so far been confirmed.

Tender documents released

Meanwhile, the Wall Street Journal reported yesterday that the Australian government has released released tender documents offering private contractors the continue the search. They would be given 300 days and have to cover an previously unexplored terrain, including seabed, using high-tech sonar equipment.

The exact search area has not been specified but it would cover a huge area of 60,000 square kilometres, WSJ reported.

The closing date for the bidding of the contract is June 30, according to the Australian government’s procurement website.

Separately, acting Transport Minister Hishammuddin Hussein said MH370’s aircraft manufacturer Boeing and engine manufacturer Rolls Royce will have to explain the tragedy to the public.

He stressed that this was their aircraft and their engine that is involved, and searchers had to act and make future plans based on their advice. This includes analysis of the satellite data from Inmarsat.

“We made our decisions based on their advice, and there will come a time when they will have to defend the advice they have given to us,” he told reporters at a press conference this morning.
