Just got back from Seattle. The flight up on Sunday was interesting.

Seattle, WA (CBSDFW.COM) - American Airlines flight 1943 en route from Dallas (DFW) to Seattle had to make an emergency landing Saturday afternoon in Salt Lake City.
The emergency landing was due to an ill passenger on board. That passenger was taken to a local hospital in Salt Lake City. The passenger’s name is not available at this time.
The flight is now en route to Seattle.

The story was a bit vague and didn't state the fact that the "ill" passenger went into cardiac arrest and they had a crew of 4 doctors and 3 flight attendants pumping the hell out of his chest. Thankfully didn't have to use the defibrilllator, but they did get it from the overhead bin. He was 6-7 rows back from me but a colleague was across the row. She said he turned blue, then grey before they finally got his heart and breathing going. Had to put a tube down his throat to help him breathe and started an IV. According to my co-worker, they said he had previous history of heart attacks. Landed in Salt Lake City and EMS and Police got on and they took him off the plane and then we were back underway to Seattle... Scary as hell. My wife (nurse) said "Cool..." when I texted her about it...
