On 5 April, a Ryanair Boeing 737-800 (registered EI-DLG) operated domestic flight FR2012 between Gran Canaria and Madrid, Spain. Just as the aircraft was about to take off, the crew noticed a (most likely faulty) cabin door open indication warning. The crew decided to return to the gate.
The flight has been scheduled to depart later this evening.
