A large, grey, four-engine military aircraft, identified as a Boeing KC-135 Stratotanker variant by its configuration and United States flag on the vertical stabilizer, is stationary on an airport tarmac. The aircraft displays the number "8" on its fuselage and "12" on an engine pylon. Several dark-colored military utility vehicles are positioned near the forward-left fuselage, and a white ground support vehicle is visible under the aircraft's nose section. In the immediate foreground, a chain-link fence topped with barbed wire separates a grassy embankment from the tarmac. The background features the urban landscape of Sofia, Bulgaria, with distant buildings under the prominent Vitosha mountain range, which appears hazy or partially obscured. The sky above is overcast or hazy light blue. The scene is illuminated by daylight. The location is Sofia Airport (LBSF) due to the identifiable Vitosha mountain background. No individuals are clearly visible performing actions.
