On 21 January, a Ryanair Boeing 737-800 (EI-EVH) operated flight FR1006 between Bucharest, Romania and London Stansted, United Kingdom. The aircraft carried 169 passengers.
At 5,000 feet, the aircraft stopped climbing and entered into a holding pattern. On a video that appeared on social media, you can see that the aircraft’s cabin starts to fill with smoke. The pilots decided to head back to Bucharest airport, where they safely landed more than one hour after initial take-off.
