CNN News:美国纽约市曼哈顿区发生爆炸事故

Thank you for taking ten minutes for CNN STUDENTNEWS.

We're glad to be part of your Thursday.

First story we have is from Manhattan in New YorkCity.

Wednesday morning a large explosion collapsed two buildings, a church and the piano store.

Officials aren't certain why this happened, but a utility company said it got a call about a gasleak just after 9 a.m.

New York's mayor says that was the only indication there was any danger.

Dozens of fire fighters arrive to search for survivors.

At least two people were initially confirmed dead, but because some were severely injured,and others were missing, the death toll may be higher.

Natural gas doesn't have a smell.

Utility companies add an odor to it, so that people can detect a leak.

If you ever think you smell it, calling the gas company or 911 is a good idea.

See if you can I.D. me.

I'm a method of gathering information.

I'm usually done online with help from the public.

I've been used in crime investigations and the search for asteroids.

I'm crowd sourcing, a way of getting info often without paying for the help.

Crowd sourcing may be able to help in the search for a missing Malaysian Airlines plane.

A company called Digital Globe has posted satellite images of the area online, thousands ofpeople are scouring them, trying to help.

Malaysia Airways Flight 370 disappeared early Saturday morning.

Less than an hour after takeoff from Kuala Lumpur, Malaysia, the plane's transponder waseither turned off or it just stopped working.

The transponder sends signals about altitude, locations and direction of a plane.

There are conflicting reports from Malaysia's government about whether the plane turned andflew in another direction.

Last night, a Chinese satellite image was released showing what might have been wreckage, butit couldn't be confirmed immediately.

The search area is bigger than the state of West Virginia.
