All:
Such medical events really do happen in an aging pilot group and are indeed sad when they do. In my club 5 years ago, we had a pilot fly for about 2 hours, execute an appropriate pattern, approach & landing, but he never exited the aircraft after pulling off the runway. One of the line kids who went out to help him reported back "He is asleep and I couldn't wake him". The EMTs could not revive him. I was the tow pilot that day.
