RAMSTEIN AIR BASE, Germany — An airman who was found unresponsive in the base pool last month is recovering at Walter Reed National Military Medical Center, Ramstein officials said Monday.

The airman, who has not been identified, was transferred to the hospital in Bethesda, Md., on Thursday. The service member is in stable condition and has shown positive signs of recovery, base officials said in a statement. The airman will do physical therapy while at the hospital, officials said.

The 86th Airlift Wing Safety Office is investigating the Feb. 21 incident, the base statement said. Safety investigations are required to be completed within 30 days.

The airman was “performing underwater training exercises in the lap pool area” when they lost consciousness, Lt. Col. Megan Mooney, the commander of the 86th Force Support Squadron, said in a statement last month. Lifeguards resuscitated the airman, who was initially in critical but stable condition and hospitalized at Saarland University Medical Center in Homburg.

The Ramstein Aquatic Center has a 25-meter fitness pool with lap lanes and a deep area with a diving board. It also has a separate pool area for children with a depth of up to 3 feet and a water slide.
