San Diegans report hearing loud boom

SAN DIEGO – A loud boom was heard around San Diego Wednesday afternoon.

A Carmel Valley resident sent a tweet at 12:26 p.m. asking if the noise was a sonic boom. Another person said their house rattled around the same time.

FOX 5 reached out to local military bases to find out if they were involved in making the noise.

Marine Corps officials said that if a sonic boom did occur over Carmel Valley this afternoon, it wasn’t them. U.S. Navy officials have not yet responded.
