When I wrote about a heart transplant, back in the early 1990s, the organ harvest team hopped into a helicopter at Loyola University Medical Center in Maywood and sped toward Children's Memorial, planning to land on its helipad and proceed to Illinois Masonic, where the heart donor was.
Mid-flight, we were waved off by Children's. The neighbors had been complaining, they said, and so they were now limiting landings strictly to cases involving patients at Children's.
The medical version of, "Sorry, not my table."
We had to land in the middle of Oz Park, in a circle of light tossed by the spotlight from a police squad car.
