Window shaped object in sky

I was driving W/SW on TX 130 South about 31 miles north of I10. It was partially cloudy with a lot of blue sky. I saw a rectangle up in the sky at about 50 degrees up and about 10 degrees to the right. The sun was about 20 degrees more to the right. The rectangle was a perfect rectangle with good 90 degree corners and straight lines for the sides. It looked like a window in the sky. It was grayish and did not move. When a light cloud passed in front of it, it then seemed to glow very bright white thru the cloud. A few seconds later a darker cloud passed in front of it and it disappeared. With the wavy road and the fact of driving an RV at 75 miles per hour I lost track of it. There were 3 other people in the car and I yelled at them to look but they were all asleep.

It reminded me of a scene in the movie "The Truman Show" where he lived in a dome that looked like the sky and a panel fell off leaving a rectangular hole in the sky. I have watched planes for years and have never seen anything like this before.

"Rectangular Shaped Object in the sky" over Silsbee, Texas on March 14th, 2020 at 9 PM:

Me and my co worker just saw the craziest thing in the sky... It was shaped like an elongated rectangle... Had one solid red light 2 solid white lights and 3 strobe lights. It was too big to be a drone.. It made no noise and it wasn't an airplane and definitely was not a helicopter... It maneuvered in some very smooth motions unlike a plane as well... It flew off then came back.. Flew off again and haven't seen it since.. Hoping it comes back to get video.

"White shining rectangle" over Houston on February 22nd, 2020 at 6:46 PM:

"MM" sent in the photo above and also wrote to Texas UFO Sightings -

I was coming out of the supermarket when I saw the sky in a blue color that I never seen before in my whole life, so I decided to take pictures. When I got home and saw it I realized that they were objects that I couldn't identify. I hope I'm not the only one who saw those objects.

[This sighting occurred at 1801 S Voss Rd, Houston TX 77057, which is the address of a Kroger grocery store.]

Top looked white bottom was copper with 3 rectangular lights

I was standing out in front of my house looking up a a passenger jet flying above my house. Saw this UFO flying much higher from the plane. It was a rectangle shape, with a copper metallic bottom with three rectangular white lights, each light was also rectangular and were evenly dispersed from from to back. From my angle it looked like the top was white.  It was going much faster than the plane and it was going North while the plane was going south.  It didn’t have wings just a rectangle with rounded corners. It did not look very deep-kinda looked like an iPhone.

Black Triangle/V-shaped reported on Rural Rd in Somerset Texas...
While driving home with my girlfriend saw what looked like a square florescent light on top of an electric power tower. As we drove closer it was almost above my car about 500ft.high a large triangle object with white rotating lights on it's bottom section about the length of a football field. Became concerned and asked my girlfriend if she saw it too. She said yes but said she saw it as rectangular shape with a round white light at each corner.

Top quadrant of moon, maybe 2000 feet from the moon. a black chain of rectangles stretched across the moon

6:54 PM , 12/22/18, I was driving home, I was on FM 2664 driving easterly.and looked up at the moon. The moon was so bright and I felt compelled to look at it.

I glanced down to make sure I didn't run off the road. I slowed down and looked back up and then I thought "what the hell is that?" when I saw the line. 1/5th the distance from top of moon was a flat black thick line.

I didn't know what it was, was black and I realized it was too sharp to be a cloud, sharply defined.

As my eyes focused it was rectangular shapes, almost all the same size, hooked together by smaller connectors. It stretched over the moon where I could not see the ends.It slowly descended, took about 4 to 6 seconds, then dropped below the moon and I could no longer see it.

I felt really strange when I saw it, elated, and when I got home I felt like I had to report it, like it was my "duty", like I had a responsibility, a burden, but not to humans. I also felt shocked like after a really good or a really bad event.

It descended past the bottom of the moon and was no longer visible.
