US Air Force veterans who served at the Nevada Test and Training Range (NTTR), also known as Area 51, are speaking out about deadly illnesses linked to radiation exposure during secret projects. Several former workers report devastating health effects after unknowingly being exposed to nuclear contamination.

One of them, former Air Force Sergeant David Crete, served at the base from 1983 to 1987. He claims an “invisible enemy” caused the deaths of over 490 personnel. During testimony before the House Veterans Affairs Committee, Crete revealed he suffers from brain atrophy. “The left side of my brain is shrinking and dying,” he said. “I’m one of the healthy ones.”

Crete believes his DNA was permanently altered from prolonged exposure to low-dose radiation. He shared that his wife had three miscarriages, and all four of his children were born with birth defects. “It was my DNA,” he said. “I brought it home.”

Due to the classified nature of their missions, many veterans have no proof of radiation exposure. Their records were “data masked,” disqualifying them from benefits under a 2000 bill signed by President Clinton for federal workers exposed to radiation.

Despite reports of health risks, a government review concluded halting NTTR projects would “be against national interests.” Veterans argue they were sacrificed without informed consent and are now seeking justice.

Two bills—The Protect Act and the Forgotten Veterans Act—have been introduced to extend healthcare coverage to NTTR veterans. Crete says the only recognition he ever received came from the late Senator John McCain, who once told him, “Your unit ended the Cold War.”

For these veterans, it’s not about exposure theories or secrecy—it’s about the right to care and acknowledgment for their sacrifice.
