"The Spaceships of Ezekiel: Was Earth Once Visited From Outer Space?" is a book by Josef F. Blumrich, a NASA scientist. In it, Blumrich describes a spaceship apparently observed by the prophet Ezekiel. It was written while the author was Chief of NASA's Systems Layout Program at the Marshall Space Flight Center. It was originally published in Germany in March 1973, soon after ufologists such as Erich von Däniken had interpreted Ezekiel's vision as a report of an extraterrestrial spacecraft. Blumrich decided to disprove the hypothesis. However, a thorough examination convinced him that Ezekiel had, in fact, seen a spaceship. He then made detailed drawings of the alien craft. He decided the technology of the builders must have been somewhat higher than mankind's at the present, and added he had seldom felt as "delighted, satisfied, and fascinated by being proven wrong." In "The Spaceships of Ezekiel," Blumrich asserts that Ezekiel's account in the Bible was not a description of a meeting with God in a prophetic vision, but one of several encounters with ancient astronauts in a shuttlecraft from another planet. In this reprint of the original U.S. Edition, Blumrich analyzes six different translations of the Bible in conjunction with his experience in engineering, and presents one possible version of Ezekiel's visions of how God—described as riding in an elaborate vehicle capable to see, attended by angels—showed Ezekiel the future, and gave him various messages to deliver.
