NBC 7 reported that construction workers at the San Diego International Airport's Terminal 1 dug up a hand grenade. The grenade was later found to be an old inert training tool that posed no threat to anyone as it did not have the potential ever to explode.

Construction workers at the San Diego International Airport’s Terminal 1 dug up a grenade Thursday, prompting a response from law enforcement.

San Diego International Airport saw a record 25.24 million passengers in 2024, making it the busiest year in the airport’s history, it was announced Thursday.

In a surprising discovery, construction workers at San Diego International Airport unearthed what they believe to be "an old, inert hand grenade" in the area of Terminal 1, a spokesperson for the Port of San Diego confirmed Thursday afternoon.

The incident did not impact the airport's operations since the ordnance did not have the capability to explode, the Port says.

Before the new Terminal 1 opens later this year, people should plan for another round of construction-related traffic interruptions when driving in and out of the airport.
