In order to prepare for sudden boarding of crew members, airline careers must ensure at least 4 or 5 vacant seats.
And, United Airlines had to think about how to deal with passengers who cannot obey what crew members say.
Lack of preparation caused this accident.
In order not to follow the similar accidents, let's make sure that your company prepares for every failure.
