We know some people who tried to quit smoking. There are times when they cannot hold their urge to smoke and say that they would really kill just for a cigarette? There is a passenger on a plane who is not kidding.
The passenger threatens the travelers and crew on her departure from Portland to Sacramento.

An instance on December 9, 2017, a Southwest Airlines flight attendant on Flight 2943 saw the 24-year-old passenger, Valerie Curbelo. She saw her taking some smoke in the plane’s lavatory.
The passenger did her best just to smoke by tampering the smoke detector.
When the crew made her go back to her seat, she then pulled an oxygen mask out of the ceiling and began shouting, going very far as to force the plane to do an emergency landing.

“I will kill everybody on this f*****g plane!” she yelled. The crew calmed her down for 30 minutes.
The pilots decided to do an emergency landing in Sacramento. Police at the terminal captured Curbelo charging her a lawful offense of giving death threats in a passenger plane.
When a columnist visited her and inquired about the incident, she didn’t have a lot of answers other than blaming it all on anxiety.
