I am still trying to grasp how a Helicopter lands in his yard and he does not grab his Krinkov.

On an earlier post here on FR it was said that a hose and CPAP machine were seen on the floor near the foot of the bed on the left side.

Both the person making the post and another person made the same comment that the noise of the machine could have covered up the noise of of the helicopter.

Before reading these posts I had seen the video that was taken in the bed room and saw a hose in that position that ran toward a object that was on the floor. The object was on the floor and near the foot of the bed on the left side.

After reading the post I saw a video or a photo that did show a hose very similar to a CPAP hose. Due to the camera angle I could not see the object sitting on the floor.

I have used a CPAP machine (a treatment for sleep apnea ). They do make enough noise that only very loud thunder will wake me.

They’re also saying that it looks like the chopper had “special” capabilities meaning some type of stealth tech.

Let's say he was using a Cpap machine. The other’s werent.

A man 2-3 kilometers away heard the helicopter

Seeing info that the US is demanding it back and telling them not sell it to China. Just unsubstantiated things on the web.

If he was also using an Oxygen concentrator along with the CPAP machine, the sound of a quiet stealth helicopter would indeed be drowned out. No one in the room with both of those machines running would be aroused by external noises unless those external noises were very loud and UNUSUAL.

On a mission trip to Jamaica a few years ago, I slept in a house without windows. There were dogs running loose and barking all night long and someone somewhere had a ghettobox blasting dance music. About the time we started getting accustomed to the noise, the roosters began crowing.

If it was common to hear gunfire from the nearby military training facilities, even the sound of gunfire in the yard would not be considered uncommon and it would not wake him up.

I personally use a CPAP machine AND an oxygen concentrator at night. The sound of the oxygen concenrtator is loud enough that I keep it in another room as far away from the bedroom as I can get it. In our old house, I kept it out on the back porch. As the oxygen concentrators get old and worn, they get even noisier.

The basic function of an oxygen concentrator is to compress the air into different strata, siphon off the oxygen, periodically release the compressed gases remaining and then repeat the entire process over again about every 20 to 30 seconds.

There is a very audible sound of the compressor running and an audible pop as the compresses air is released into the atmosphere to begin the next compression cycle.
