Flight attendants of Reddit, what's the scariest thing you've witnessed while on a plane?

Let me set the scene for you: it is 9 o clock at night on Hawaiian Airlines and the flight attendants have just finished their coffee service. I'm sitting down, trying to get some sleep. The in-flight entertainment, however, had just begun: about three rows in front of me, a couple is having an argument. The girlfriend is screaming at the boyfriend about how everything is awful. Favorite quotes for the girlfriend (the boyfriend said about three words during this time):

"I AM LITERALLY WHISPERING RIGHT NOW" (Heard from 10 rows forward and back)

"Look what you've done. Everybody is looking at us, and you're making a scene."

Several times during this argument, the flight attendants came over and tried to ask her to calm down. Finally, one flight attendant walks to her row and says:

"Ma'am, I'm going to have to ask you to remain quiet or I will escort you off this plane."

Woman: (laughing) "We're over the Pacific Ocean."

Flight attendant: "Yep."
