A massive power outage that forced the evacuation of the USS Hornet Sea, Air & Space Museum during a July 4 celebration has left the museum scrambling to make up for revenue lost from what should have been one of its biggest fundraisers of the year.

The aircraft carrier was anticipating taking in about $65,000 from the event, which offered museum-goers a sweeping view of local fireworks from the ship’s flight deck.

The actual estimated loss, since the evacuation began before most visitors arrived at the museum, is about $40,000, said Mike McCarron, a USS Hornet spokesman.

The amount includes money spent on advertising and for musicians, who were paid up-front.

“It was a huge loss to us,” McCarron said. “But it was also a huge loss to the community. A lot of people were looking forward to spending July 4 aboard the ship.”

The outage began about 3:30 p.m. and impacted about 4,300 customers of Alameda Municipal Power in the city’s West End.
