I photograhed my wife for a picture by the lighthouse. When developted we noticed "something" that was not there before.We arrived home from this vacation in Cancun. We did not develop the picture for a week or two. When we did develop it, we noticed a white "something" in the background of a picture close to the lighthouse in Garrafon, Isla Mujeres. On closer magnification it looks like a "spaceship" about 10 feet long and 200 feet up in the air. It looks almost like the small scout ships in the movie "Independence Day". I will send the pictures tonight 4-11-00. I work in the propulsion division as an aerospace engineer for the Department of Air Force. Note: It looks like the "something" is preparing to enter the water, as there is a circle forming on the water below it.((NUFORC Note: We received the photograph, and an enlargement of the object. We are unsure of what the object is, but our first guess would be some kind of large sea bird, probably a pelican. However, that is only an educated guess.))
