Large Structure Class UFO with "Drone/Repair" Class UFO.

Large ufo structure class sighting. Additional drone type ufo doing repairs along edges of large structure. In the space where the large structure sat, there was a clearly definable dark, very dark area, which was extremely distinguishable from the sky which was starting to get lighter by the minute due to the sun rising. There is no possibility that it was a cloud, it was precise and had an exact shape. I couldn't take an adequate picture, but I drew a picture of the approximate shape. If it weren't buried In a pile of old files, I would post it. However, the large structure wasn't the only thing that convinced me it had to be an alien origin. In the center of the larger object it appeared a set of lights began moving to possibly open up a what I would assume to be a hangar type area? And then a light appeared and began moving along the outer edges of the overall object very precisely. Moving most likely at hundreds of miles an hour. It would stop every so often and "light up" the area it looked as though it was repairing the hull of something for only fractions of a second to a second or two at most. Every so often it would move much quicker between what I would call " apparent repair points" and changed directions as it went along the structure multiple times, with very precise movements. The overall structure took up about 1/4-1/3 of the sky that was visible within our eyesight and leaning back to see as much as we could. My girlfriend and stone cold sober roommate witnessed in addition to myself. I probably should have posted this much earlier but I have been skeptical of what I saw considering how crazy it was. Also have been searching for any account of an identical sighting. I've never seen anything like this before and this is coming from someone who has seen a dozen different ufos with a dozen different people. It made me feel incredibly small. To anyone who doesn't believe this story, that's up to you. But trust me I know what we saw and I am only posting this in hopes of creating a better account of sightings such as this. I probably could add more detail and try to make this post more legit seeking but that's again not my point.

NUFORC Note:

Witness indicates that the date of the sighting is approximate. PD
