Bulgaria had started the conflict hoping to revise the partition of Macedonia settled after the First Balkan War, only to be crushed by its former allies.<\/p>\n<p>The treaty forced it to hand over large territories \u2014 most of Macedonia among them \u2014 to Greece, Serbia, and Romania, leaving Bulgaria with just a narrow strip of Aegean coast. The loss settled into the national memory as a lasting grief, steering the country&#8217;s foreign policy and irredentist hopes for decades.<\/p>\n<h2><strong>August 10, 1915 \u2014 Bulgaria&#8217;s First Homegrown Aeroplane Takes Flight<\/strong><\/h2>\n<p>At Bozhurishte airfield, a commission from the Ministry of War inspected a biplane designed and built by Asen Yordanov, a gymnasium student still in his teens who had picked up his technical skills as a volunteer mechanic during the Balkan Wars.<\/p>\n<p>After a clean test flight, the commission pronounced the aircraft \u2014 nicknamed &#8220;Express&#8221; \u2014 fully airworthy and original, formally recognising Yordanov as an inventor. He later built a remarkable career in the United States, helping design the Douglas DC-3 and contributing to Boeing&#8217;s B-17 and B-29 bombers.<\/p>\n<p>Head back to <strong><a
