Carrie Fisher Suffers Major Heart Attack On Plane

The actress, best known for her role as Princess Leia in the original Star Wars trilogy, went into cardiac arrest near the end of the flight. Medically-trained passengers on board administered CPR for the final 15 minutes before the plane landed at LAX. Passengers reportedly on board the plane claim that the actress was not breathing for ten minutes, and they were administering CPR up until the moment the plane landed. The aircraft landed and paramedics rushed Fisher to a nearby hospital.

According to an audio recording between airline staff and air traffic control, which you can listen to embedded below, Fisher was not responding from efforts to revive her.

“We have some passengers, nurses assisting the passenger. We have an unresponsive passenger, so they’re working on her right now.”

We have no further information at this time, but our thoughts are with Fisher and her family. We will update this post when we hear more, but for now, we wait and hope that everything is okay. May the Force be with her.
