The extreme zoom of the camera makes everything look close together. In reality it's probably quite far from most other planes.

>Especially with what appears to be no ground troops surrounding the plane.

Why would you have them stand outside to guard the plane when the airport is already fenced off, and has surveillance/security? Even if they do need people guarding it, it doesn't make sense to stand outside. Waiting inside or in a nearby SUV would be much more comfortable for the guards.
