Saucer-shaped object captured flying over the Irazu Volcano in Cartago, Costa Rico

I was with my girlfriend visiting Irazu Volcano national park in Cartago Costa Rica on February 24, 2016. The weather was really nice. Very good sun light not cloudy.

This Volcano is 3400 meters of altitude above sea level close to the biosphere. So we were above the clouds. Like when you fly on airplane. The sky was really clear so at 11:00 am on that altitude part of the sky was light black.

We were taking pictures of the volcano and the landscape. The clouds looked like a white sea but I noticed close to one of the mountains some clouds with different forms, so I started to take pictures there.

Once we finish the tour we headed back home. While I was checking the pictures I noticed one black circle above the mountains I noticed before.

On the picture you can see the object completely clear. It looked like a circular saucer with 2 little antennas one on the top of it and like one on it's tail. Mufon case 74756.
