I was homeless living in a tent with my GF at the time. Woke up to a loud metallic hum. Sat up and saw a craft hovering in the field

I sat up quickly and it was just hovering there. As soon as I looked at it it started to move. Flew right past me into the corner of the field paused for a second then took off through westmoor Park. All the while making this loud metallic rumbling hum and then off into the sky. I was breathless to say the least. I look down at my girl friend and she is still snoring. I literally sat there for 15 minutes just in shock with what I had witnessed. There has not been a day that has gone by where I haven't thought about it. I emailed the principle of the school begging him to check his cameras but never got a reply. I drew a map of how it happened and told my girl and parents but don't know what else to do. I am a decorated combat veteran of the afghan war and have very good observation skills. This is not my first ufo encounter but it is by far the closest and most baffling thing I have ever seen. When I woke up to the hum it was hovering maybe 10 feet from the ground and shining a bright red light. Then it performed its maneuvers. The whole time about 10 ft from the ground until it reached the edge of the park. Then it shot into the sky.
