Chapala Jalisco México avvistamento

On Sep/11/2004 Chapala Jalisco, MÈxico at about 15:30 pm. My family and I went to dinner to the real Chapala Hotel (Ajijic Jalisco, Mexico).

We ate and then went to table next to the pool, and I saw an object with a shape like a saucer with an American-ball inside. I said look an UFO and it moved up an down nearly of surface of the lake, we saw too an exhaust coming from the object and suddenly go down to the surface of the lake and it would navigate on the water for about 50 mts. then disappeared.
