it's not completely clear to me, but i think all transport activity occurs at a single geographic location somewhere on the planet...and i'm assuming that if it was over belgrade there would be more sightings but really not sure. i'll just post quotes regarding a physical, mindal and spiritual energy pole.

39:5.13 When celestial beings are to be enseraphimed for transfer from one world to another, they are brought to the headquarters of the sphere and, after due registry, are inducted into the transit sleep. Meantime, the transport seraphim moves into a horizontal position immediately above the universe energy pole of the planet.

so i guess assuming these are the same location and it doesnt move i'll say no its not a transport seraphim...but could be a secondary midwayer.
