hi - from the pictures you have linked - it is virtually impossible to tell what the range of the object is - be it aircraft or UFO
it may " appear " to be over a building - or in a no fly zone - but thats just an illusion from a 2D image
the plane is only on the same compass bearing as the building - determining its range is far more complicated
it can be done , but for a cityscape like that you need to know
1 - position of the camera
2 size of the building
3 size of the object
knowing the position of the camera alows you to use a map to determine the range to the building
knowing the zize of the building allows you to measure ho many pixels its image occupies - this how many pixels / m it occupies -
and lastly - from the size of the object - obviously its size on the image can be compared to the size of the building - and voila - you now know if
its indeed above that building - and if no - if its infront or behind it
simples
