I once had a military helicopter fly directly over a dig I had and circle it at a height so low I could throw a stone at it. There was a guy leaning out of the side pointing down at the hole. I was hiding under a tree. After flying around it 3 times they just flew away. It happened a day after I had been sending multiple text messages to a pinoy team member because he was talking too much about our operation. So maybe everything you say really is true. It's just hard to believe they could have the funding, know-how, equipment and manpower to pursue the enormous amount of communications that must be going around about treasure sites. The military never came back to my site. I never had any problems. Were they just passing by on the hunt for NPA and noticed my dig? Who knows...
