Flight tracking data from Flightradar24 showed that the flight circled above Faro Airport before successfully landing.
Ryanair released a statement indicating that the flight had to return to Faro Airport shortly after take-off due to a technical issue with the aircraft. The plane landed safely at Faro Airport but experienced a minor issue with one of its tires on the runway.
