What was the occasion for the surprise fireworks display in SF over the weekend?

A surprise fireworks display in San Francisco on Saturday evening startled many residents, as the event went unannounced. The 12-plus minute show celebrated the 50th anniversary of Computers and Structures, Inc. at Pier 27, leaving some local residents puzzled and frustrated by the lack of prior notification. Witnesses described the intensity of the display, with one resident noting that the booms rattled windows and even startled wildlife. The Port of San Francisco is contemplating measures to enhance communication regarding private fireworks events, as many residents support the idea of public notifications.

One local expressed a desire for more transparency, especially if such events could disrupt their evening routines. The fireworks show, produced by Pyro Spectaculars, was comparable in scale to large public displays typically seen on New Year's Eve. The company behind the event acknowledged the inconvenience caused and expressed regret for the lack of invitations. Residents are encouraged to sign up for notifications about future waterfront events to stay informed.
