While descending towards Shannon Shannon Approach advised that the Mode-C transponder signals were unreliable. A short while later the crew queried whether ATC now had a proper transponder signal, which ATC confirmed. The aircraft landed safely on Shannon's runway 06.

The aircraft remained on the ground for 11 hours, then continued the journey climbing to maximum FL270 and reached London with a delay of 11.5 hours. The aircraft remained on the ground in Gatwick for another 21 hours before resuming service.
