Yes, people can be removed from airplanes for being rude, disruptive, or threatening others. Airlines have specific rules and policies in place to ensure the safety and comfort of all passengers and crew members on board. If a passenger's behavior is deemed to be disruptive, aggressive, or poses a threat to the well-being of others, the airline and its crew have the authority to take appropriate actions, including removing the passenger from the flight.
The decision to remove a passenger is typically made by the flight crew or the captain, who has the final authority over the aircraft. If a passenger's behavior is severe enough to violate aviation regulations, local laws, or the airline's policies, they may be taken off the flight before takeoff or even after landing.
In some cases, passengers who are removed for disruptive behavior may face legal consequences or be banned from flying with that particular airline or even other airlines in the future.
It's essential for all passengers to adhere to the airline's rules and guidelines, treat fellow travelers and crew members with respect, and maintain appropriate behavior throughout the flight to ensure a safe and pleasant travel experience for everyone on board.
