The curvature does look sort of uncanny but then again, we don't often see photos from this vantage point. While some of these are wide angle photos which can have lens distortion, photo processing tools also have lens correction options to remove such distorions. Looking at the photos with the aircraft's wings visible, it doesn't appear as though there's much lens distortion remaining. One of the coolest aspects of the photos to me is the way you can see terrain in a fairly typical aircraft view underneath and still see the curvature of the horizon toward the edges. Since it's on a photography-centric site, I was a little disappointed there was no discussion of the camera gear or lens selection. I was also hoping to see camera EXIF metadata alongside the images which would typically reflect lens type, focal length, shutter speed, aperture, etc.
