PORTSMOUTH — Portsmouth International Airport officials on Saturday afternoon said as many as 30 military aircraft – including several F-16s – remain at the airport.

The officials said they were not allowed to say when the aircraft from a southern military would depart. They were initially said to be leaving the airport at Pease International Tradeport on Friday and then their departure was later estimated to be sometime in the early Saturday morning hours.

“The information for the noise advisory was the only information we received and the airport will not be provided updates,” Airport Director Paul Brean said Friday about the military aircraft that evacuated their base to avoid Hurricane Michael and landed at Pease. “Flights are always subject to weather and operational logistics so I cannot confirm a departure time.”

A number of area residents watched the F-16s and other aircraft fly in from the fence surrounding the airport on Wednesday.

When the jets do end up flying out of Pease, residents around the area should expect to hear it when they leave, Brean said. The F-16s “need to use their afterburners when they take off,” he said.

Sandra McDonough, operations specialist and community liaison at the airport, cautioned residents about the same likelihood late this week.

“Upon departure, the pilot is required to utilize the engines’ afterburners as an operational necessity with this aircraft. Consequently, area residents may perceive a significant noise event as a result of jet aircraft departures,” she said in the community noise alert.
