I heard a pan pan call on 132.250 Kansas City Center here in KS. a Jet Blue 957 has a female in cardiac arrest and a doctor and nurse on board helping . they're diverting to MCI. That got my attention. https://flightaware.com/live/flight/JBU957
more screenshots of the Jet Blue 957. I am listening to the online radio stream for the airport and hear the medivac meeting them.
