Fellow passengers held ⁠on to Serbian national ​Ljubisa ⁠Karovic as he was pulled out the window. He was injured and hospitalised.

Video footage shot by passengers on board the aircraft showed the remnants of a shattered window on the right hand side of the cabin with oxygen masks dangling from the ceiling – testimony to the rapid depressurisation of the 18-year-old Boeing 737 aircraft shortly after it took off at 6.01am local time.

The plane was flying at 15,000ft when passengers said they heard a loud bang before the aircraft started to descend, spending 30 minutes burning fuel before it landed safely at Thessaloniki Airport.
