Low-Flying Helicopters Over Greater Eureka Spark Questions; USCG Provides Answers

Residents from Samoa to Eureka, and from Murray Field to Kneeland, reported low-flying helicopters and increased noise on the evening of Wednesday, Feb. 4, leading to speculation online about what might be unfolding overhead.

Some witnesses reported seeing multiple helicopters at once  and asked whether a rescue or other operation was underway.

According to Commander Josh Smith, chief of response for the United States Coast Guard in Humboldt County, the Coast Guard had aircraft flying that night as part of scheduled training missions.

“We did have flights that night working primarily in the vicinity of Samoa, Eureka, Murray, St. Joseph’s, Kneeland,” Smith said.

He also confirmed that three Army helicopters were observed flying north through the county that evening, but said their presence was unrelated to Coast Guard activity. Smith said Coast Guard crews saw the Army helicopters pass over the Eureka–Murray area but had no involvement with them. “I can’t speak to what [the Army helicopters] were doing or where they were going. That’s just not something we get advanced notice on,” Smith explained.

Many residents associate Coast Guard helicopters with active rescues or medical emergencies. While that is often the case, Smith emphasized that regular training flights are conducted daily, year-round.

“We schedule training flights every day of the week, 365 — even on Christmas or Thanksgiving,” he said. Aircraft availability and emergency calls can affect scheduling, but “generally speaking, we schedule training events every day.”

Those training missions include practicing approaches to local facilities such as St. Joseph Hospital and area airports. Some maneuvers require lower altitudes than a typical landing profile.

“Some maneuvers have a lower approach than others,” Smith explained. “If we are simulating rotor failure, that maneuver demands an extended approach from a lower altitude than a normal one. It’s going to generate more noise in the area, but it’s also a critical skill that we practice.”

He said such training ensures crews can safely operate if mechanical issues occur or if they must land under degraded conditions.

Night flights and operations in poor weather are also essential.

“We don’t always have the luxury of choosing when we have to fly,” Smith said. “People get injured [and] sick, …at all times of day, and we need to be able to respond effectively to that.”

He noted that the public expects a responsive and credible medevac service. “Part of that is constant practice in challenging conditions,” he said, including nighttime flying, fog, rain, and offshore hoists in the eight- to ten-foot seas that are common off Humboldt’s coast.

“It’s unfortunately a perishable skill,” Smith added. “If you don’t practice, you can’t do it when it really matters.”

Smith acknowledged that increased helicopter noise can be disruptive, especially near residential areas adjacent to airports or medical facilities.

“I’m not trying to discount the concerns about flying friendly,” he said. “That’s also something we try to do.”

While the noise and low approaches drew attention, Smith said the flights reflected preparation rather than crisis. The same maneuvers that can rattle windows during training are the ones crews rely on when responding to real emergencies along Humboldt’s coast and in its rural communities.
