OKLAHOMA CITY — Two airmen were killed Thursday in an accident involving two jets during the landing phase of a training exercise at Vance Air Force Base in northwestern Oklahoma, a military official said.

The crash occurred shortly after 9 a.m. at the base in Enid, about 65 miles northwest of Oklahoma City. Two airmen aboard one of the T-38 Talons were killed, Col. Corey Simmons, commander of the 71st Flying Training Wing, said during a news conference Thursday afternoon.

He said the two airmen in the other T-38 Talon were not hurt.

Simmons struggled to control his emotions as he described as much as he could of what happened and how the approximately 1,200 military personnel on the base were coping with the tragedy.

"We are a close-knit family," Simmons said, appearing to choke back tears, "and when tragedies like this occur, every member of the U.S. military, Vance, Enid, feels it."

The military will not release the names of the service members who died until 24 hours after their families have been notified, Simmons said, citing military protocol.

An Air Force safety board is investigating, and it typically takes 30-60 days to determine the cause of such accidents, Simmons said.

He declined to speculate on what might have happened.

“Only … for the purity of the safety investigation," Simmons said. "I don’t want to try to guess. I wasn’t out there when it happened.”

Simmons also said he does not know if the planes collided.

"I know that there are two airplanes that are off the runway right now at Vance Air Force Base," he said. "How they got to that point, I've got to let the investigation play itself out."

In a statement, Sen. Jim Inhofe, R-Oklahoma, said he was deeply saddened by the accident and loss of the airmen, and offered his prayers to the Vance community and the pilots’ family and friends.

But he also said Congress must do more to make sure training and readiness programs are funded well enough to avoid more such incidents. Inhofe said the defense authorization bill passed last year included funding for training and flight time, repairs and modernization of aircraft, and more policies meant to improve safety, and this year’s bill will authorize more such funding.

“Over the last decade, more active-duty service members died as a result of training-related incidents than in combat operations,” Inhofe said. “While training-related casualties are down this year, even a single instance is too many. We’ve known this is a problem that can’t be solved in a year, and more must be done.”

Military aviation is inherently dangerous, and our pilots and pilot trainees rely on training to ensure they can do their mission,” Inhofe continued. “That’s why it’s so important that Congress ensure training and readiness programs are well-funded. This is the least we can do to make sure our airmen can safely meet current and future threats and to prevent incidents like what happened at Vance today from happening again.”

The base describes the T-38 Talon on its website as “a twin-engine, high altitude, supersonic jet trainer.” used in a variety of jet pilot training roles. It is one of three types of aircraft, along with the T-1 Jayhawk and the T-6 Texan, used for pilot training at the base.

Air Force officials said an Air Force pilot ejected successfully before a jet trainer crashed in western Oklahoma in August 2018. The pilot was found safe, while the jet crashed and exploded about 70 miles west of the base. Investigators said the pilot ejected after the jet developed engine trouble, apparently caused by a bird strike.

Simmons said the 2018 crash was the first major accident at the base since 2000. He said there are typically 800-1,000 landings per day at the base as part of about 225 daily training missions.

Simmons said all flights at the base are shut down and that planes would likely remain grounded on Friday.
