Here is an interesting incident that occurred a few days ago in Bulgaria. A UFO was seen over farm land near some very tall power lines and it was being monitored by a military aircraft. The UFO seems to not be in any kind of hurry to move and and the jet seems like its only there to identify the craft to those back at base. I don't think any military will risk deliberately shooting at an alien craft. Back during the battle of Los Angeles when a fleet of silver disk UFOs flew over LA and hundreds of anti aircraft guns hit them, but could not harm them...its clear aliens can protect themselves. My mom witnessed that one.
