Final point correct Jacko - Bill Pix still with us.
John Mardon (note correct spelling) was a rotary mate before getting a fast jet crossover, so figures in my logbook lots - and we lost many braincells together, although he nevr looked old enough to drink legally!
It was indeed his lungs that needed changing, but the state of the art then meant that you had to do a heart and lung job, which leaves servicable ticker on the shelf at stores. Which was duly given to (I think) a London taxi-driver who was indeed at the funeral....... quite odd to meet him.
And then there was the Chinook mate who hit wires in Australia and provided 2 servicable kidneys - I guess they get well used in Oz, we were all amazed they were still usable.
