Drone pilot Manish Maharjan helped Nepal's rescue teams find missing people after last week's disastrous floods.
無人機飛行員Manish Maharjan協助尼泊爾救援隊,在上週災難性洪水後尋找失蹤者。
Sometimes he used the drone's speaker to shout to people trapped on hillsides or play music for them.
他有時用無人機上的揚聲器向被困山坡的人喊話或播放音樂。
But he said searching for hundreds of workers inside a power plant tunnel was a completely different challenge.
但他表示,搜尋發電廠隧道內數百名工人的工作,是完全不同的挑戰。
Maharjan said the tunnel was full of mud, like toothpaste in a tube, with no empty spaces.
Maharjan說,隧道裡充滿泥漿,就像管子裡的牙膏,沒有空洞或空曠空間。
He is also a filmmaker. He joined the Nepali army rescue the day after the flash flood on August 26.
他同時是電影製片人,在8月26日山洪暴發後第二天加入尼泊爾軍隊救援。
The flood has killed more than 1,000 people in Nepal and Tibet. Thousands are still missing.
這場洪水已造成尼泊爾和西藏超過1000人死亡,數千人失蹤。
Maharjan said they used loudspeakers to call to trapped people. Sometimes they played songs and waited for a reply.
Maharjan說,他們用麥克風揚聲器向被困者喊話,有時播放歌曲並等待回應。
He said this worked in several cases and helped find people.
他說這在幾起案件中奏效,幫助找到了人。
The flood from the glacier collapse caused wide damage to roads, buildings, bridges, and hydropower stations.
冰川崩塌釋放的洪流,對道路、建築物、橋樑和水電站等基礎設施造成廣泛破壞。
At least 900 workers are still missing from 12 hydropower projects. The projects are buried in mud and debris. About 500 people are believed to be trapped in the power plant tunnels.
至少900名工人仍從被泥漿和碎片掩埋的12個水電項目中失蹤,據信約500人被困在發電廠隧道內。
Mohan Kumar Dangi is the head of the Independent Power Producers' Association. He said that some workers in the tunnel managed to call for help during the disaster.
獨立電力生產者協會主席Mohan Kumar Dangi表示,災難發生時,隧道中一些工人成功呼救。
But it is still unclear if rescuers have had any contact with them.
但尚不清楚救援人員是否與他們有任何聯繫。
Maharjan operated a thermal imaging drone in the tunnel. He said the search was challenging because the tunnel was hard to enter and had no open space.
Maharjan在隧道中操作熱成像無人機,他表示搜索因隧道難以進入且沒有空曠空間而充滿挑戰。
He said he could only fly into long, straight tunnels. Once there was a curve or a turn, operating and searching became much harder.
他說,只能飛進又長又直的隧道,一旦有彎道或轉彎,操作和搜索就更加困難。
On Monday, at the Rasuwagadhi hydropower project, he flew the drone to the end of the tunnel. He found no signs of life.
周一在Rasuwagadhi水電項目,他成功將無人機飛到隧道盡頭,但沒有發現生命跡象。
He said the tunnel was full of mud and debris. Looking at it, you could only imagine the power of the flood.
他說,隧道充滿泥漿和碎片,看著它只能想像洪水的威力。
