Here's a remarkable sighting by three scientists from Down Under. Note the detailed description. The devil's always in the details.
*********************************************************************************
UFO sighting 1970 Tanami Desert Northern Territory
Dated: August 1970
Location: Mongrel Downs Station near WA border half way between Alice Springs & Darwin
Names have been witheld by request.
Three very highly educated and qualified people:
"One Geophysicist; Two Geologists, all involved in Mineral Exploration and Mapping, employed by a mining company in Tennant Creek working in the Tanami Desert. One of the witnesses has since gone on to become a member of parliament in Western Australia.
Land marks - Granite & Rabbit Flats Northern territory.
At the time of the sighting we were on a property called Mongrel Downs Station close to the western Australian boarder. At the time of the sighting we stopped our two land rovers at a location known as the Three Officers Hill, which are several hundred feet high in an otherwise flat landscape for virtually hundreds of miles.
We saw 2 UFOs same design size with pulsing flame or lights yellowish flashing from underneath "exhaust" at about a second between each flash the distance was about only 300 yards from our position at about eye level with an above ground level altitude of only several hundred feet.
It appeared as if they were on a "Sunday afternoon cruise" the UFOs traveling at slow speed maybe 50 miles per hour were visible until they disappeared across the horizon they took a good minute or to to pass our position and disappear.
Design
Circular with a cabin on top with portholes both visible both with pulsing flame/light flashing at about 1 second intervals the size according to my friend T our Geophysicist about thirty feet in diameter. The colour was silver the machines were silent and no exhaust smoke but the underneath exhaust flashed about each second.
From our position we were looking north the UFOs were traveling west to east at low speed and low altitude, therefore we had a remarkable dress circle view of the objects.
The atmospherics was a typical Northern Territory winters day, the time was about 3.00 p.m the sun was just to the back of us, not a cloud in the sky visibility about 20 miles.
The UFOs were traveling at a slow speed and maintained that slow speed and low altitude maybe for 500 yards above ground level despite the time it took to pass over our dress circle position. They traveled one behind another.
The motion of the UFO traveling ahead appeared to be vibrating at the front the other following close behind in smooth motion perhaps in the slip stream (was the front one wounded???)
Several days latter we returned from our bush location and called into Mongrel Downs Station and informed the owners of these events.
The owner of Mongrel Downs Station informed us that several months earlier strange lights were observed coming from the area we had been in late one evening
They informed the Department of Civil Aviation Darwin of the happenings and we called on R.A.A.F Officers for details and were subsequently and officially informed “Surveyors were working in the area (“That's Bollocks'). In those days surveyors could not work at night besides any human species wondering around that ultra remote area would be known and permission to be on the property would be sought by the owner.
The Government explanation was a load of bull Diane. I remember this event as though it happened just yesterday.
They are among us observing the bloody mess we are making of our beautiful planet.
Food for thought.
For example should you draw a line between the US submarine base at Exmouth Gulf of Western Australia and the US base at Pine Gape in Alice Springs one could maybe construed that was the approximate line those space vehicles were traveling on ???.
Almost immediately after our sighting I purchased Bruce Cathy's book Harmonic ECT and in his book he has pictures of these things, some were absolutely identical to what we saw on that sunny afternoon at Mongrel Downs Station Tanami Desert Northern Territory mid August 1970."----

Reminds me of the constant mocking by a poster with the initials MR, of any and all suggestions put as possible outcomes of some of these sightings you like to dig up on u tube.
