                SPANGDAHLEM AIR BASE, Germany – A patch rests on the sleeve of Bulgarian air force Maj. Iliyan Antonov during a Bulgarian air force visit Sept. 12 here. The tour serves as a way for the United States and Bulgaria to learn and exchange ideas about each other’s air force to ensure air dominance in any contingency operation.
