A Bulgarian military jet crashed during a drill for an air show near Plovdiv on Friday, killing both pilots aboard and triggering a fire that authorities moved quickly to contain.

The aircraft, an L-39 Albatros training jet, went down shortly after noon near Graf Ignatievo Air Base in southwestern Bulgaria, about 150 kilometers from Sofia, according to the Ministry of Defense. The crash happened during rehearsals for an air show tied to the anniversary of Bulgaria joining NATO.

Officials said the impact ignited a fire on the ground. Emergency crews were dispatched to the scene, and state broadcaster footage showed black smoke rising above the airfield as fire trucks moved in.

The Ministry of Defense said an investigation had started into what caused the crash. A statement from Prime Minister Dimitar Glavchev’s office said he was on his way to the base after the accident. Defense Minister Atanas Zapryanov canceled the air show following the crash.

The accident came as Bulgaria prepared to mark the 20th anniversary of its NATO membership the next day, along with 35 years since the MiG-29 was inducted into the Bulgarian Air Force, according to state news agency BTA.

Training aircraft such as the L-39 are used widely in military aviation for pilot instruction and drills. Friday’s crash turned a ceremonial rehearsal into a fatal emergency and raised immediate questions about the condition of the aircraft and the circumstances of the training run.

Authorities did not immediately release the names of the pilots or provide further details on their identities. The defense ministry also did not say whether other aircraft were involved in the drill or whether the crash affected other base operations.

What is clear from the official account is that the aircraft was participating in a planned rehearsal, not an operational mission, and that both crew members died at the scene. The air base is one of Bulgaria’s key military installations in the country’s southwest, and the incident briefly drew national attention as smoke and emergency response teams were visible at the site.

The investigation is expected to focus on the aircraft, the training conditions and the moments before impact. For now, the crash has left Bulgaria’s anniversary weekend preparations overshadowed by a fatal accident at one of its main air facilities.

What to watch

The next test will be whether authorities release a verifiable timeline, identify the agencies responsible for follow-up, and publish updates that reconcile early figures with later findings. Initial reports during fast-moving crises often change as hospitals, local officials, investigators and families compare records. That makes attribution and transparent corrections as important as the first headline number.

For readers, the key distinction is between what has been confirmed in the source material and what remains unresolved. Further reporting should look for named official statements, independently documented evidence, and clarity about the legal or operational response. It should also track whether emergency measures reach affected communities and whether promised investigations produce public findings. Until those details emerge, the safest interpretation is narrow: the article establishes the reported event and the authorities' current account, but it does not settle every disputed cause, responsibility or longer-term consequence.
