Thomas Ricardo was 23 when he disappeared from Half Moon Bay, California, on May 22, 1998. He was known to fly small aircraft, and eyewitnesses reported seeing a plane that he may have been piloting and that possibly went down into the ocean off the Half Moon Bay coastline.

Searches including aerial surveys found no wreckage or definitive evidence of what happened, and his fate remains unresolved. Authorities have classified the case as a missing person investigation and list him as an endangered missing person. His family continues to seek closure and any information that could explain the disappearance.
