Came across the following time on UFOs, et al blog about the 1973 experience of Contactee Enrique Castillo Rincon. Rincon lived in Colombia. His experiences include tall aliens in diving suits (a not so unusual motif) and the craft he saw -- “domed ships” -- appeared to have come from a nearby body of water. Like many Contactees, Rincon received some form of telepathic messages from “several groups” of individuals in various areas.
