A Colorado witness in Arapahoe County reported watching "a giant white, triangular-shaped object" crossing the sky from horizon to horizon in about two seconds about 10 p.m. on April 27, 2013, according to testimony from the Mutual UFO Network (MUFON) witness reporting database. The witness was at home lying on a back porch and watching the sky when the object was first seen. "I had just focused my eyes on an airplane when suddenly a giant white, triangular-shaped object appeared," the witness stated. "It was directly above me. It was enormous and it was moving amazingly fast. It traversed the entire sky - horizon to horizon in about two seconds. It was hard to reference the size, exactly, but I got the sense that it was a very large object very far away." The witness described the object. "This thing was pushing the limits of physics. The corners of the triangle were rounded and the lights were big circles - the light was yellowish-white, and it was kind of dimly lit. I really got the sense that it was very far away, way up in the sky." Read more..
