My name is John and this happened when I was 10 or 11 years old, so it would be around 1978 or 1979. While I was younger I was involved with the church and this happened one Sunday morning while I was helping set up for Mass. I was the only one in the building setting up when I heard a loud bang coming from the choir loft at the other end of the building.
Curious, I stepped out from where I was and called out “Hello” and there was no answer.
So, I figured that the person just didn’t hear me and was just doing what they needed to do in getting ready. I was looking up towards the choir loft to see if I could see the person and there was no one there and figured that something had just fallen down and the noise just echoed throughout the church. I was just going through the normal rational ideas to come up with a reason for what I had just heard.
