An American Airlines flight bound for Los Angeles made an emergency landing in Nebraska after the pilots believed someone was trying to break into the cockpit, authorities and the airline reported.
Later, the clarification was issued that it was a false alarm caused by a technical problem in the Embraer ERJ 175 aircraft of SkyWest.
"The flight returned to the airport out of an abundance of caution and landed without incident. There was no real risk to the crew or passengers," SkyWest added in a statement.
The incident occurred on the night of Monday, October 20, when Flight 6469 , operated by regional subsidiary SkyWest Airlines , took off from Eppley Airfield in Omaha, bound for Los Angeles.
Shortly after leaving the ground, the pilots declared an emergency and decided to return to the airport after hearing noises and knocking at the cockpit door.
However, the subsequent investigation revealed that the incident was due to a failure in the internal communications system between the cockpit and the flight crew.
The intercom, which allows flight attendants to speak to the pilots, had been accidentally activated, generating static and confusion.
Unable to establish contact, the flight attendants banged on the cockpit door to report the failure, which the pilots interpreted as an attempt to break in.
According to an American Airlines spokesperson and statements from the Federal Aviation Administration (FAA) , the incident was caused by a failure of the intercom between the cockpit crew and the pilots.
The incident prompted a brief deployment of emergency crews at Omaha Airport and reopened a debate about the sensitivity of U.S. air safety protocols , where any irregularity in the cockpit immediately triggers alerts for possible hijacking attempts .
