At first I was almost tempted to dismiss these as some sort of bug or other flying creature. The person had told me they had not seen anything at the time they were taking the photos, and in my opinion how could you not see this? Though they also told me they were taking these photos to finish off a roll of film, so there is the chance that they weren't really paying attention to what's in the sky but just hitting the shutter until the film had stopped advancing. But I was showing these to some friends on Sunday and one of them actually recognized the object.
They used to work out near Kearney and had seen the object in the air several times. They described it as large craft, longer than the length of a football field and made hardly any sound. The small orangish lights on the object appear to be engines, according to my friend. Though we were unable to determine what is causing the pinkish glare, though I imagine it's from the sun as it was near sunset when the picture was taken. The photographer thinks it was a glare from a porthole or something, though I'm not sure how that is possible. I've sent it to a few photograph experts I know in hopes of getting an opinion. I'm also sending these to the local MUFON investigator here in hopes that he can find out what this is. As always, anything I find out I will post here.
