ALIEN investigators have been inundated with a spate of bizarre UFO sightings said to have happened in the past two days across the US. Shocking UFO events over the last 48 hours include the sighting of 25 orbs, what looked like a “flying bus,” and a triangle UFO tailed by military helicopters. Events started in Texas, on Saturday morning, according to reports received by the US-based Mutual UFO Network (MUFON). An unnamed witness filed a report about two high-speed bright lights, in an undisclosed location. It said: “I was wide awake early Saturday morning. “I looked up in the sky where I usually tend to and saw two bright non flashing lights. “Similar to stars, but slightly brighter. “They caught my eye because they were both traveling north at a high rate of speed. “They had a good distance apart, but were going the same exact speed. “They were way to high to be aeroplanes and were going too fast. As they passed over they both started to dim and I lost sight.” Next a triangle UFO with central orange light was seen being tailed by military helicopters over Springfield, Missouri, also on Saturday. There were SIX further UFO sightings reported to MUFON yesterday. A witness said they and a friend also saw two bright orbs over Plum City, Wisconsin, on Sunday. They both watched as they discussed it on mobile phones. The report said: “I realised that what I was looking at was something that I have never seen before. “Shocked, I stood there and watched the whole time still talking with my friend on the cell phone as we both viewed the two orbs that were hovering in the sky then one before the other dimmed out of sight.” Yesterday, a witness in Grand Forks, North Dakota, also saw two bright lights. Their report said: “I’m still trying to figure out what these lights in the sky were. “I’m in the city limits, but around eight or 8.30pm, I saw two more stars moving in the sky. “I just came inside right now to report that. What is it? “I never heard about this from anyone else. “it’s amazing, I wish I had a good camera or at least some night vision binoculars.” The same night a witness in Dover, Pennsylvania, reported: “I was looking up at the stars then noticed something bright shoot from a star up and disappear.” In Hillsboro, Oregon, a witness claimed to see “six objects below the clouds rotating around each other.” The report said: “My wife pointed out a group of lights, possible reflection of sunlight off the objects, which were ahead of us and underneath the cloud canopy. “There were more than six objects rotating, diving, climbing around each other.” MUFON has not released any footage, despite the couple claiming to video the event. They said there were other witnesses and they saw a similar event in 2016. Yesterday, in broad daylight, two people claim to have seen the bizarre spectacle of 25 blue or white bubble-like orbs with wings that were in a formation together, over Kansas City, also in Missouri. The report said: “Plain as day and clear as a bell we saw 25 orbs in a frenzy and all working the same area. “These objects or orbs were kind of clear to blue in colour. “They initially looked to be big bubbles and then my friend and I both noticed that these orbs had small wedge-like wings on them. “Kind of like a bubble with sharp V-shaped wings attached to the centre of the orbs.” They tried to film them, but the camera would not work, and they faded away.
