3 rectangular objects were roughly 400ft off the ground for roughly 20 minutes above an oil tank battery setup that i watch over in the oilfield in midlan county. me and a fellow co worker then watch them ascend silently to about 1000ft above it and continued to hang stationary in the sky for an hour and ten minutes. they were pulsating red from the inside. they were massive, roughly 200-250ft tall and 100ft across. the 2 rectangular objects on the end stayed stationary while the middle object continued to move in between the to end objects continuously. we had our natural gas flare going and you can clearly see in the pictures provided the light reflecting off the outside of the objects. this was the second time we have seen the same objects on 2 different dates. it was a brand new oil well location we just opened up and were monitoring here in midland county. they were clearly and easily visible to the naked eye and hovered completely silent for over and hour and a half and then just as fast as they appeared they seemed to disappear without movement. they seemed to just instantly go invisible. one of the objects had the red pulsating lights traveling from one tip of the object to the the other tip, the light was clearly coming from the inside of the craft and not an exterior light, i've never seen anything like it before. on the video evidence provided please turn your brightness up all the way as we had alot of light interference while trying to film. the objects will be up in the right hand side corner.
