“United Airlines sent a scathing memo to its pilots warning that alarming behavior of its flight teams must stop now.

The memo reveals some cockpits are dysfunctional, with pilots ignoring their copilots warnings about an ‘unsafe situation.’

The memo, obtained by CNN, said the behavior was ‘unacceptable,’ and was just part of a stern warning to flight teams about conduct that was putting passengers and planes in potential danger.”
