Unknown objects behind planes in Afghanistan.I was taking photos of aircraft as they landed at Bagram Airbase Afghanistan. I never saw the objects while I was shooting; I only saw them after they were on my laptop for editing. They appear as brown spot almost football shaped, I blew up the images and they seem to have form and mass but I am no expert. The only adjustment made was auto color done with picture project software that I use. I first thought this was dust until I noticed it was only on two of my photos and they were taken almost one hour apart all the photo in between have no dust at all, and the lens was never cleaned during shooting. I can send the photos and metadata with lat and long but the time is off on my camera. These photos were taken around 0930 to 1100 UTC/GMT +4:30 hours.
