A well documented incident found at the Vulcan Science Directorate and Space Council, but against common Human knowledge, occurred in 1957 when a Vulcan survey ship crash-landed just outside Carbon Creek, Pennsylvania.
Sent to investigate the launch of Earth's first artificial satellite, Sputnik, the vessel's impulse manifold began to malfunction during the third week of intelligence gathering, forcing the crew to attempt an emergency landing. As a result the captain perished in the crash, leaving command to T'Mir. In addition to T'Mir, the two other survivors of the ship crash were Stron and Mestral. (ENT: "Carbon Creek")
