Overview

• Prime Minister Rosen Zhelyazkov told parliament that flight records showed no pilot concern, a brief five-minute hold, and consistently good signal quality.
• The European Commission had initially said jamming occurred and relayed Bulgarian suspicion of Russian involvement, a claim Moscow denies.
• Deputy Prime Minister and Transport Minister Grozdan Karadzhov said civilian and military data provided no facts to support a silenced GPS signal.
• Independent tracking analyses indicated no GPS loss over Bulgaria and about a nine-minute delay, while the same aircraft reportedly encountered jamming a day earlier over the Baltics.
• Earlier reports described pilots reverting to paper charts and terrestrial navigation, and experts cited by RFE/RL said any interference in such a scenario would likely originate near the airport as the EU pursues RNSS protection measures and sanctions tied to jamming and spoofing.
