The Ryanair plane set off from Palma’s Son Sant Joan airport at 6:43 am, heading to the German city of Memmingen.
By 7:20 am, the pilot had been forced to make a U-turn and return the 148 passengers on board back to safety after a fire alarm went off in the aircraft’s landing gear.
Emergency services were activated at Son Sant Joan in case the fire on board prevented the aircraft from making a safe landing, Spanish news agency Europa Press reported.
None of the passengers required medical attention for inhalation of fumes or anxiety.
Airport security are currently investigating what caused the fire alarm to go off.
