Peña's report generated a fair amount of excitement, but it was only the beginning. Not long afterwards, a Madrid author of a UFO book received several photographs in an anonymous mailing. The photos were of a craft similar to the one reported by Peña, and bearing the same symbol. Within a few weeks, "a leading Spanish contactee named Fernando Sesma Manzano became involved when he began receiving lengthy, typewritten documents which purported to come from a spacefaring race called the Ummites."
