CNN News:馬航最新報道 雷達曾追蹤客機飛往馬六甲

New information in the search for a missingpassenger plane, but still no closure for families.

This is CNN STUDENT NEWS.

There's little hope and a lot of grief for the familiesof 239 people.

That was the number onboard Malaysian Airlines Flight 370, which disappeared early Saturdaymorning.

Word came out yesterday from Malaysia's government that somehow the plane's transponderwas turned off.

That's an instrument that transmits altitude, location and direction.

Malaysia's air force was still able to track the flight as it apparently turned, and flew over theStraits of Malacca, hundreds of miles off course.

Unfortunately, that's where the answers end.

As of last night, there was still no sign of the plane.

We can show you what it's like to search the area near the plane's last known location.

This is no easy task.

This C-130 plane has been carrying out regular search and rescue missions since flight MH- 370 disappeared.

It's the first time the minister for defense and transportation and the chief of defense forcehave been out to survey this massive operation.

They invited CNN to join them.

I have to put this life jacket on because we are now descending to just 500 feet above sea level.

Lying low, the doors are opened for the search to begin.

We flew past the number of ships, scouring the sea for the plane, those on board or any cluesat all to what's happened.

I just want to find the plane, you know, at all costs and as long as we are still standing and aslong as people are out there, praying for us, we will continue to, and this is something that I willnot stop.

This is what I promised to families.

We flew to the Malacca Straits to the west of Malaysia.

For 16 ships surveilling this area, that's more than 12,000 nautical square miles.

They are joined in the air by 14 air crafts.

And that's just the area to the west of Malaysia.

There are more than 30 aircraft and more than 40 ships in the entire operation.

As we look how to cross these vast expense of water, far into the horizon, holding his hat inhis hands, the minister tells me he's over overwhelmed.

When you are looking for something, this-sea, it's a reality check.
