This year, ISM-USA, which runs the Regatta, has changed the fireworks show. Although the Regatta has used the fireworks company Zambelli Fireworks International, of New Castle, Lawrence County, for last two decades, officials will be using a new company, Pyrotecnico, also of New Castle, said ISM-USA Senior Vice President Michael Dongilli.

Mr. Dongilli said they wanted to try something "different" this year to "elevate the showmanship."

Zambelli Fireworks International President Doug Taylor said he was "disappointed" by the Regatta's decision to not use his company.

"We were surprised because we had done it for so many years and we had done it vey well for so many years," he added. "We are determined to be back shooting with them" next year.

Mr. Dongilli said the Regatta is simply trying out the company this year and will re-evaluate the situation for next year's event.

Pyrotechnico did not immediately respond to a request for comment this afternoon. But during a press conference earlier in the day, Pyrotecnico officials said their show will last 25 minutes and will feature 22,000 fireworks devices.
