In April 2009, we were with my family at the Tzintzuntzan Ruins in Michoacan, Mexico, and noticed this craft hovering in front of the mountain to the northwest of us. It was there for a minute or so and simply disappeared in front of our eyes. There were two witnesses including myself. I was an aircraft mechanic in the Marines and have seen virtually every type of aircraft we possess, and understand their flight characteristics. It was pretty amazing! This region is a UFO hot spot, and the locals all have stories of seeing craft like this. This is also not the first time we have seen these types of craft while living here, but the first time to snatch a picture of one. You can clearly see the disk-shaped craft in the middle top portion of the photo.
