Also, I thought that somebody were testing jet engines at the Kuching International Airport but from the direction of the sounds, it wasn't coming from the airport but from the opposite direction. Also, according to the law, nobody should be that crazy testing anything that loud in the early morning.
The following video has a very good audio quality of the sound and I confirmed to you that we heard exactly the same sound on the morning of Jan 11 and Jan 12. I bet you agree with me that the sounds seemed to be of somebody's snoring but yet it was from a far distance and the source seemed to be from the sky. Please ignore the sound of motorcycles and cars in the background.
Was the strange sound related to the recent earthquake occurring at about the same time in Acheh. Or can anyone enlighten us regarding the source of the strange sound on that particular day.
