Jacques Vallée

Jacques Vallee is an astronomer who was born in France, and specializes in the study of unidentified flying objects (UFO). He received a B.S. in mathematics at the Sorbonne and an M.S. in astrophysics at Lille University. He later received a doctorate in computer science at Northwestern University.Vallée co-developed the first computerized mapping of Mars for NASA and was a developer in the ARPANET.

He participated in the 1997 Physical Evidence from UFO Reports symposium.

Vallee developed a taxonomy for UFO observations, which includes interactions between humans and aliens. *AN1: Viewing anomalous lights or explosions in the sky that do not affect the witness or the environment.

• AN2: Reports that show lasting effects such as flattened grass, poltergeist activity or anomalous photographs.
• AN3: Cases that include entities. This could include ghosts, yetis (Abominable Snowman), elves, spirits and cryptozoology.
• AN4: The witness reports interaction with the entities within the reality of the entities themselves. This type of experience could include near-death experiences, religious visions and out-of-body experiences (OBEs).
• MA1: A UFO that drops, maneuvers, loops.
• MA2: A UFO that includes a physical interaction with the environment while performing drops, maneuvers or loops. An example of this would be seeing a UFO near a power plant.
• MA3: Witnessing entities on board a UFO while performing the above mentioned maneuvers.
• MA4: The UFO witness observes the listed actions and goes through a transformational experience during the event.
• MA5: The UFO witness suffers serious or injury as a result of seeing a UFO in the sky.

The character of Claude Lacombe, played by François Truffaut in Steven Spielberg’s 1977 film "Close Encounters of the Third Kind" was patterned after Vallée.
