As the Financial Times claims, the plane carrying Ursula von der Leyen landed in Plovdiv on Sunday using paper maps.

The Financial Times, which published this information, cited three officials familiar with the situation.

As reported by the British Daily Mail, when approaching the airport in Plovdiv on Sunday afternoon, the plane carrying the official ran out of electronic navigation aids, the Bulgarian Air Traffic Control Authority confirmed.

GPS"jamming" or "spoofing", which interferes with access to the satellite navigation system, is a tactic that Russia has used in the past to destroy civilian life, the British media pointed out, recalling that this technique was historically used by the military and intelligence services to protect sensitive locations.
