This thing was gigantic... it was probably the size of 10 football fields. it was lined with 100+ windows and inside was very very bright. it did not make a single sound. i was in my backyard and my dog came running to the back door and started barking non stop. i was coming in to quiet him from waking up my household but decided to look up at the sky one last time and that's when i saw it. i grabbed my binoculars and couldn't believe what i was seeing. i have a picture but do not know how to upload
