Is there a doctor on board?
An aviation engineer had something of a busman's holiday this week when he was called on to repair the airliner bringing him back from a break in Menorca.
iPM has been thinking about airline passengers being asked to give the crew assistance since we heard from the father of an oil rig safety engineer. His son watched in shock as a fellow passenger was taken ill and stopped breathing.
"It appeared that the flight crew did not have adequate basic training, felt incompetent to render CPR and had to call on the services of the passengers."
Have you or someone you've travelled with been taken seriously ill mid-flight? Have you given medical aid to a passenger?
Or perhaps like the aviation engineer you've lent your professional expertise to the flight crew. Let us know.

We asked Scott Adams, the oil rig safety engineer, about what happened. After asking listeners if anyone had had similar experiences Martin Miles-Moore and Dr Halcyon Leonard got in touch.
Martin is a physiotherapist who recently responded to a call as he returned from a ladies basketball tournament in Berlin. And Dr Halcyon is a retired GP who could never have guessed the consequences of answering a call ten years ago on a flight to Oman.
They each told me their story, beginning with Scott.
