OC Boardwalk Arch near North Division Street in Ocean City.
A loud boom heard Monday morning in Ocean City was likely caused by military jets that frequently fly over the area, according to Jessica Waters, a spokeswoman for the town.

The boom was heard around 11:40 a.m., she said.

Jets out of Navy bases in Norfolk and Patuxent River in Southern Maryland often fly over the beach resort from time to time and can caused disturbances for Delmarva residents.

"We certainly do experience it from time to time," Waters said.
