Charlie 253 declared a Mayday 70 miles off the west coast at 10.30 this morning and was trying to head for Shannon. She eventually landed safely at Kerry airport shortly before 11.00. Believe there must have been a fire of some description as Rescue 115 was asked to stand by in case any crew needed hospital for smoke inhalation. Rescue 115 has now been stood down. Thank god everyone got back safely.
