Laughlin Air Force Base has grounded all air operations through the Thanksgiving weekend, following the crash of a T-38 Talon late Monday, News Radio 1200 WOAI reports.
One pilot was killed and the other is in critical condition after the two seater came down near Amistad Dam on the Rio Grande. It has not been released whether the pilot who lost his life was the instructor or the trainee.
47th Flying Training Wing Commander Charlie Velino said the goal of the base now is to support the families of the pilots.
"Our Airmen and their families are incredibly important to us and our top priority. For now, we will focus inward to make sure that our base community rallies around those who are suffering and need our support," Col. Velino said in a statement posted on social media.
He said flying operations will resume on Monday.
"The pilots who train at this base are truly the tip of the spear in securing our national defense, and we are grateful for their choice to serve in that pivotal capacity."
An Air Force incident investigation team is looking into the cause of the crash.
Northrup Grumman, the manufacturer, says more than 72,000 Air Force pilots have trained on the T-38 since it was introduced in 1972. It says some 500 of the supersonic trainers are still in active operation.
