Flight crews are ready to deal with any unexpected emergency onboard, such as unruly passengers.

When a male passenger suddenly grabbed the hair of a female passenger seated in front of him on Alaska Airlines Flight 221, bound from Oakland, California, to Portland, Oregon, on February 1, a flight attendant came to the lady’s rescue.

Unable to pry the man’s hands off the woman’s locks, the male crew member started punching him in the throat and torso. That forced the passenger to let go of the woman’s hair.

Another passenger caught the disturbance on camera, and the video went viral on social media. The plane returned to Oakland Airport, where the attacker was arrested and removed.

Cops are even better trained to deal with emergencies.

When a New Jersey State Police (NJSP) trooper arrested a woman driving to Jersey City on Route 78 in Florham Park for allegedly being under the influence of alcohol on October 17, 2017, the driver later sued the agency, and the case was tried by a jury.

According to the court papers on the case, cited by the New York Post (NYP) in a report on 10 February, when the officer found Cheryl Lynn Rhines, 48, with vomit on her face, unable to answer questions, her face drooping, and unable to control her body and motor functions, the officer accused her of “playing games” and arrested her.

Two hours later, someone at the police station recognized that Rhines was having a stroke and called an ambulance to take her to the hospital.

Delayed treatment resulted in the disability of Rhines, who can no longer work and requires around-the-clock care, her family said in their lawsuit, the NYP reported.

The jury found the police at fault in January and awarded Rhines nearly $13 million in compensation.
