What happens when a passenger tries to break into the cockpit on a commercial flight

C14 Desk, 8 minutes ago

Two attempts to breach the cockpit within a matter of days have renewed the debate over aviation security in the United States. Since the September 11 attacks, cockpit doors have been reinforced and procedures tightened, but experts warn that vulnerabilities still remain. So how do flight crews deal with unruly passengers, and what awaits someone who tries to take over an aircraft?

A passenger’s attempt to break into the cockpit during a commercial flight is considered one of the most serious offenses in aviation and can end in immediate arrest, federal charges and heavy fines. Last month, on a Frontier Airlines flight from Puerto Rico to Chicago, a 51-year-old passenger tried to open an exit door and later attempted to breach the cockpit. According to court documents, he shoved his shoulder against the cockpit door, assaulted a flight attendant who was off duty, and was eventually restrained by passengers and crew. The plane was diverted for an emergency landing in Miami, where the passenger was arrested.

Days later, another incident was reported on a United Airlines flight from Chicago to Minneapolis, in which a passenger tried several times to reach the cockpit. In that case too, the flight was diverted and landed at an alternate destination.

Why is it almost impossible to break into the cockpit?

Since the September 11, 2001 attacks, all commercial aircraft have been fitted with reinforced cockpit doors, including locking mechanisms and reinforced frames. Security experts told CNN that these doors are designed to withstand forced-entry attempts, including kicks and heavy blows. Even so, there is one vulnerability, the moments when pilots have to open the door during the flight to use the restroom, eat, or change crew members.

In the United States, the installation of secondary barriers in front of the cockpit has been promoted in recent years. This is a kind of locked gate placed between the passengers and the cockpit door, allowing pilots to leave the cockpit without exposing it directly to passengers. Several airlines, including Southwest, United, American and Delta, have already begun installing the barriers on their new aircraft.

How do crews deal with unruly passengers?

Flight attendants and pilots undergo specialized training to deal with violent passengers, intoxicated passengers, or those in psychological distress. In most cases, the first step is to try to calm the passenger, but when there is a threat to flight safety, the crew is authorized to physically restrain the person. In some cases, other passengers also help. On the Frontier flight, a passenger with a background in martial arts helped subdue the suspect until landing. In addition, armed air marshals operate on some flights, and under a special program in the United States, there are also pilots who receive training and carry weapons to protect the cockpit.

What is the punishment?

An attempt to break into the cockpit or assault crew members during a flight can lead to serious federal charges. The FAA can impose fines of up to $37,000 for each violation, and in some cases criminal indictments are also filed.

According to FAA data, in 2025 there were 1,621 reports of unruly passengers, and 130 enforcement actions were taken that led to fines totaling about $2.3 million. Despite the incidents, no one has managed to breach the cockpit of a commercial aircraft in the United States since the September 11 attacks.
