The Space Capsule 5 requires to be heavily insulated. This insulation is also a sound prove insulation. It is very hard for me to figure out how can this mentioned noise energy be able to travel inside the space capsule from the outer space? I believe this mentioned noise inside the capsule #5 is further confirming my suspicious that the Chinese space capsule has wiring problems. And it is this same wiring problem that had triggered the Fire Alarm in #7.
