Uruguay: Alleged UFO Over Atlántida

What are we to make of these photos of so-called "invisible UFOs" (anomalous objects not apparent to the photographer at the time the photo was taken)?

On the one hand, they are held up as proof of alien visitation; on the other, decried as blurry shots of local avian life. Only one thing is for sure: we haven't seen the last of such images.

Today's photo, courtesy of Luis Burgos of the FAO and his team (http://ciencia-ovni.blogs) was taken by Graciela Aguirre on January 27, 2010 on the Atlántida coastal road in Uruguay -- on the opposite side of the River Plate from Argentina.

A bird? A plane? Superman? You decide.
