On July 20th, 2017 a witness reported to MUFON that they had a strange encounter with a triangle shaped craft in the area. They reported watching a triangle-shaped object silently move overhead with white lights on all three points. The witness was returning home from dinner around 9:40 p.m. while riding on their motorized wheelchair. Their transportation van was in the shop for maintenance so this was their only means of transportation.
On May 25th, 2017 a witness near a town called Sunnyside in Washington state reported that a triangular shaped object followed his vehicle along a rural road. The sighting occurred around 10:50 pm as the witness was returning home after a long day of work. The witness regularly takes the back roads home, this evening Factory Road, when he noticed an orange light near two red lights in a triangular pattern above him, but in the distance.
Magnetohydrodynamics (MHD) is quite the mouthful, but seems to be one of the latest forms of propulsion and may help explain a huge variety of UFO sightings. MHD relies on magnetic properties of electrically conducting fluids to provide lift and thrust. Some common fluids used are plasma, liquid metal, salt water, and electrolytes.
