(a) There is no English-language original for this report.
(b) "他对美国之音回忆说，他们搭车到比利时的一个港口，凌晨时分逐一悄悄地爬进停放在那里的卡车后面货柜内，然后被反锁在里面，至于这是什么货柜，是否为集装箱，似乎就全看运气了。王安登上货柜，稍后出发的谢平则进入了集装箱，'你就那样感觉到空气越来越稀薄，直到快无法呼吸了…' 幸好，谢平听取了其他有经验偷渡者经验，随身携带了一把槌子和一只镙丝刀。他开始打洞，但同行中有人反对，唯恐打洞声音太大会被发现，'人都快死了，还怕什么? 。' 谢平的槌子和镙丝刀救了集装箱内20多条生命，包括他自己。"

(集装箱，在香港及台湾一般称为货柜，在中国大陆一般称为集装箱)
(ii) "感觉到空气越来越稀薄"
(A) That is ridiculous. Oxygen makes up 20% of air, but accumulation of 5% carbon dioxide causes one to die. In other words, long before oxygen is used up, a person faints or falls asleep when CO2 increases and died when the increase reached 5%. That is why people die in the container without banging the container to warn the driver. I am a biologist by training, and is well aware of this fact. This phenomenon is called carbon dioxide narcosis in medicine, and one can kill a small animal humanely by throwing dry ice into an enclosed container..
(B) The report does not mention the years these Fujianese men did the trip. For a long time, US has installed x-ray to look into a container.

("In the aftermath of the terrorist attacks on September 11, 2001, US Customs Service began developing antiterrorism programs to help secure the United States. Within months of these attacks, U.S. Customs Service had created the Container Security Initiative (CSI). * * * CSI is now operational at ports in North America, Europe, Asia, Africa, the Middle East, and Latin and Central America. CBP's 58 operational CSI ports now prescreen over 80 percent of all maritime containerized cargo imported into the United States")
