Charles James Hall is an American author and former Air Force weather observer whose self-published Millennial Hospitality series describes what he says were repeated meetings in the 1960s with the Tall Whites, tall, pale, humanlike beings he places in the desert mountains near Indian Springs, Nevada. The account rests on Hall's own testimony, and no released government record or independent witness has corroborated it. It has nonetheless made him one of the best-known personal-contact claimants in modern UFO literature.

By Hall's account, given at length to the journalist Paola Harris, he enlisted in the Air Force in July 1964, trained as a weather observer at Chanute Air Force Base in Illinois and was assigned to Nellis Air Force Base near Las Vegas in the spring of 1965. He says he spent most of the next two years as the duty weather observer at Indian Springs, the auxiliary field on the Nellis gunnery ranges that was renamed Creech Air Force Base in 2005. He says he was then posted to Binh Thuy Air Base in South Vietnam for a year and was honorably discharged in May 1968.

Hall says his encounters began in late May or early June 1965, that the beings kept an underground base in the mountains north of Indian Springs with the knowledge of Air Force personnel, and that a female he calls "the Teacher" spoke with him. Gaia's series Alien Files: Re-Opened summarized his story as a base on government land granted in exchange for advanced technological insight. He also describes a second group he calls "the Norwegians," whom he says he met in Wisconsin between 1961 and 1963; he says they have fewer teeth than humans and slightly webbed toes, and he suggests they may come from near Barnard's Star. Hall has acknowledged that he has no photographs, logbooks or other physical evidence of his own.

Hall published the first Millennial Hospitality volume in 2002 and the second and third in 2003 through the self-publishing house 1st Books Library, followed by fourth and fifth volumes from AuthorHouse in 2007 and 2012. The third book, The Road Home, includes an appendix setting out what he calls the "Hall Photon Theory." The series was adapted as the film Walking with the Tall Whites (2020), and it is commonly listed among accounts of contact with Nordic aliens, the fair, benevolent humanoids of earlier contactee lore.

Interest in Hall revived in 2026. NewsNation's Ross Coulthart said in May that he found Hall's claims of interacting with a nonhuman intelligence "interestingly credible." Reddit users argued that the books, written years before recent whistleblower testimony, anticipated themes now common in UAP debate, and others searched satellite imagery of the mountains near Creech for the base he described, while an X account circulated his description of the Norwegians in October. Hall remains the sole source of the Tall Whites, a name that has traveled from his self-published memoirs into cable news and the wider vocabulary of alien "types."
