UFO odors suggest hydrocarbons fuel

摘要

Retired Nuclear Engineer (UK) Abstract: Odor descriptions in 16 close-encounter reports are summarized and attributed to low-temperature oxidation products of three hydrocarbon fuels. NO_2/N_2O_4 from atmospheric nitrogen fixation is discussed as another odor-ant. Odors are usually not experienced in UFO sightings, since the object must be nearby, and the witness must be within the downwind dispersion plume. Even in close encounters with disc UFOs, only about one out of three cases includes perception of odors. Witnesses generally report an unfamiliar, nauseating, pervasive and oppressive smell, pungently irritating to the mucosal tissues of eyes, nose, and throat. Depending on the magnitude of integrated exposure, immediate effects may include dizziness, upset stomach, and vomiting.
