We almost never see large aircraft visiting the Sofia Airport. When I heard the roar, I thought it’s a helicopter or some US military aircraft with a hundred propellers. Looked up, and I was genuinely surprised to see a Jumbo Jet. We had A380 landing here once and it made it to the news. This would be the first time I hear 747 landing in Sofia. Also, flying over the city center with full throttle, probably not the best.

It’s a flight from Sofia to Djibouti. I couldn’t find any information about it but I would put my money that it’s an evacuation route for people who want to leave the Gulf area.
