MH370 With the search-and-rescue mission entering into its third week today, the case of MH370 is set to become one of the greatest mysteries in aviation history.

And with officials still clueless as to the whereabouts of the aircraft, acting Transport Minister Hishammuddin Hussein is also running out of information to feed the hordes of journalists, both local and foreign.

However, he vowed not to relent.

Responding to a question, the minister stressed: "I will never give up... This is my assurance to the family members."

"I am given more hope with the number of countries involved and the assets deployed. Personally, I am not looking back," he added.

Hishammuddin also reiterated that he could understand the anguish of the affected families and their desperate thirst for a closure.

On another question regarding the cost of the search-and-rescue mission, Hishammuddin said that none of the countries, including Malaysia, involved in the operation had discussed this.

"That is the best part," he said, and added, "It did not even cross our mind" when a subsequent question was posed on whether the Malaysian government had a rough estimate.

Earlier, Hishammuddin had described the events which had unfolded since the aircraft went missing on March 8 as a "roller coaster ride, with many twists and turns."

Once again, the minister reiterated that the images of objects in the Indian ocean as revealed by Australia remains as the most credible lead.

(During the briefing, he received information of a Chinese satellite having captured images of objects in the southern corridor).

Hishammuddin also denied that the Malaysian government was withholding information regarding the aircraft as alleged by certain quarters.

Below are salient points from the briefing:

The search

• Search in the northern corridor to date sees no sign of MH370
• Search for the object captured by satellite released by Australia on Thursday in the Indian Ocean remains fruitless
• China's satellite captured 22mx13m object in the Indian Ocean and are deploying ships to investigate
• Search in the Indian Ocean in the next few days is being threatened by Tropical Cyclone Gillian
• The category one cyclone is developing near Christmas Island

The transcript

• Malaysia Department of Civil Aviation said transcript of MH370's final communication released in the media was "inaccurate"
• It refuses to say if the transcript was entirely false

The cargo

• MAS reiterates that lithium-ion battery in MH370's cargo was not dangerous and complied with aviation rules
• Preliminary investigation indicate cargo had nothing to do with MH370's disappearance
