The crew reported a bomb-bay fire in their mayday.
I have personally been told by senior figures at Kinloss that no mayday call was made by the crew of XV230. A call was made that was described as something else (name escapes me now) but it was some sort of priority call to report a problem but not a mayday call.
I have no intention of adding further to the speculation around the incident just wanted to clarify that one point.
