This was a photo I took myself from the airplane, no tricks, no photo shop. I used a digital camera.
[...]Or who was at the airport at the time?[...]
If I read well enough between the lines, I think you've found the correct part of the image to look at
You can deduce from the image itself what's special about it, though not easily. It becomes easier if you zoom in with photoshop or whatever else you use to edit images. The photo was taken too far away to distinguish people, so no, it's not about who is in the photo or at the airport at the time.
If it's too hard to see on the current image, I also made another photo that's more zoomed in (optically). I also photographed the object in question from other angles, both on the ground and from the plane, but that will make it too easy
Bloopy: are the 3 entities abstracts?
No. That should be a helpful clue!
Hmm. Are they people? Or fictional characters? (I'm starting to think you might be talking about the big bang theory, the series - more specifically, the main characters - the physics hint is accurate then, but totally threw me off)
