It has been 11 years since Arizonans saw something in the night sky that remains a topic of conversation to this day. On March 13, 1997, a swath orbs in a V shape known as the Phoenix Lights passed silently overhead. Sightings launched a debate that continues. Were they military flares, an unknown government experimental aircraft or something other-worldly? Dr. Lynne Kitei, a Paradise Valley physician, wrote a best-selling book on the Phoenix Lights, and was executive producer of an award-winning documentary about the subject. An updated version of the 80-minute documentary - with new information, new interviews and new footage - will be shown Sunday at the Harkins Shea 14 Theatre in Scottsdale. "It has been a labor of love and a work in progress since we started," Kitei said. The new versions includes interviews with Apollo 14 astronaut Edgar Mitchell, who was the sixth man to walk on the moon. "He created or founded the organization, the Institute of Noetic Sciences, which combines science and spirituality, which has been my work in this right along with the Phoenix Lights," Kitei said. There is also an interview with a now-retired Phoenix Police Department 911 operator who fielded calls about the lights that night, confirming the sighting's timeline and sharing details provided by callers. "It also confirms that the police were very well aware of what was going on. They actually did some things that have never been shared before, which is exciting in itself," Kitei added. The documentary includes an interview with a commercial airline pilot, who along with his wife, saw the lights and said they were definitely not flares, and revelations by former Gov.Fife Symington who witnessed the sighting. Kitei said UFO sightings have been accelerating worldwide thanks, in part, to technology, and she hopes that in her lifetime, the question who was the driving force behind the Phoenix Lights and other sightings will be answered. She said people are capturing sightings on their cell phones and are actually looking because they are more educated about the topic.
