A Massachusetts Air National Guard officer says authorities are still searching for the pilot of a fighter jet that crashed in Virginia and do not know whether the pilot may have ejected.

The single-seat F-15C crashed in the mountains of western Virginia on Wednesday morning.

Col. James Keefe of the 104th Fighter Wing of the Massachusetts Air National Guard said at a news conference in Westfield, Massachusetts, that the missing pilot is an experienced flyer. He said the plane was on its way to New Orleans to have a radar installed as part of routine maintenance.

Keefe said he had not received confirmation that anyone had reached the crash site.

Officials say the pilot reported an inflight emergency, then lost radio contact.

No injuries were reported on the ground as authorities located the crash site through heavy smoke on a mountainside.

The pilot of the single-seat F-15C was with the 104th Fighter Wing of the Massachusetts Air National Guard in Westfield, Maj. Matthew Mutti said.

The jet was on a standard training exercise to receive a system upgrade and had no munition onboard, said Mutti, from Barnes Air National Guard Base. He didn’t say where the jet was headed or release the pilot’s name.

The pilot made a report of an inflight emergency, then lost radio contact, officials said.

“Information on this incident is developing rapidly, and we are not going to speculate on what occurred or the status of the pilot,” Col James Keefe, 104th Fighter Wing Commander, said in a statement. “We are hopeful that the pilot is OK, and the pilot will be in our thoughts and prayers.”

Just before 9 a.m., residents near Deerfield — with a population of just 130 people, about 135 miles northwest of Richmond — say they heard a series of explosions-like booms.

“It’s the loudest noise I’ve ever heard,” 63-year-old Rebecca Shinaberry, who lives on a farm about two miles away, said. “(It) just shook the ground, and from my house we could just see a big plume of smoke.”

Turkey farmer A.D. Shinaberry said that from the first two booms, he thought a plane had broken the sound barrier. But 10 seconds later he heard a third boom — the crash, he said.

Then, “it was like a mushroom, black smoke came up,” Shinaberry said.

From the smoke, Virginia State Police said, they located the crash site, in a heavily wooded but level area adjacent to a mountain in the George Washington National Forest.

A deep crater and a large debris field are on the site, and state police are searching, spokeswoman Corrine Geller said.

“It is probably five, six miles from the crash site to the nearest civilization,” Keefe said. “It’s deeply wooded, and a lot of hills and mountains.”

“We are not going to speculate on what occurred or the status of the pilot,” Keefe said. “We are hopeful that the pilot is OK.”

He said the plane was flying about 30,000 to 40,000 feet — “pretty high” — when the pilot reported the emergency. Pilots are trained to release equipment when ejecting, Keefe said, so it was likely the pilot did not have his radio.

The area around Deerfield is rural with rocky, steep terrain. Authorities were gathered at a volunteer fire station outside the crash site. Next to the fire station, helicopters took off and landed to help in the search.

F-15s are maneuverable tactical fighters that can reach speeds up to 1,875 mph, according to the Air Force website. The F-15C Eagle entered the Air Force inventory in 1979 and costs nearly $30 million, the website says. The Air Force has nearly 250 F-15s.

Several F-15s have crashed over the past few years in various states. In at least one, the pilot ejected safely. Causes included failure of a support structure for the jet and pilot error.
