Today we're back in the mountains,and we're gonna set off our own full-scale avalanche to see its deadly effects.
今天 我们回到这片山区 准备制造一次真实的人造雪崩 亲眼目睹一番致命的后果
If all goes to plan,the whole mountainside will come crashing down.
如果一切依计而行 整个雪坡将排山倒海直冲下来
To trigger the avalanche,the team will drop four 28-pound charges from a helicopter.

Hello, Dave. This is Danny, over.We're already heading up the mountain.
你好戴夫 我是丹尼 完毕 我们正出发前往雪山
And we're hoping for a big one,but it's way too dangerous for any human.
我们本来想搞点大动作 但是这对血肉之躯太危险了
Instead, we'll place a life-sized replica skier in the avalanche fall line.
取而代之的是 把拟真滑雪者放在 雪崩行进的范围内
It's fitted with a transceiver which is used by backcountry skiers.

It sends out a signal which rescuers can track,even if it's buried deep.
即使深埋地底 它发射的信号 也能让救援者循踪而至
Once the avalanche is triggered,we'll send in the search-and-rescue guys,see how long it actually takes them to reach the dummy.
雪崩一旦发生 我们会派出搜寻救援队 看究竟要久才能找到假人
And then the team are gonna bury me in the snow and see if I would have lasted long enough for them to reach me and make it out alive.
而后 工作队会将我埋进雪中 看我是否能支持到他们找到我 并成功的死里逃生
Once the danger zone is cleared,we call in the helicopter.
一旦此地危险解除 我们招来直升机
All right, we're gonna turn to the left there,right around there to the left.
好了 我们将在此左转 就在此向左
Okay, Nick, you ready?Yeah. Yeah, go ahead and throw bombs.
好了吗 尼克你准备好没 好了 开始 扔炸弹吧
Hovering 20 feet above the summit,they're taking their positions.

Now they start their bombing run.Igniter on.Bombs away.
现在要开始引爆了 点火 投弹
The heli team will drop four charges,But the clock's already ticking.
直升机小组将投向四枚炸弹 计时已经开始
These bombs have two-minute fuses.

The chopper must be 500 yards away from the explosion,or the shock wave will knock them out of the sky.
飞机必须距离爆炸点四百五十米远 否则冲击波会把他们从天上轰下来
