B-36 Peacemaker

The Convair B-36 Peacemaker was a type of aircraft flown on Earth in the 20th century.

It was a strategic bomber developed and operated by the United States Air Force during the Cold War against the Union of Soviet Socialist Republics in the 20th century.

History
In September 1972, a trainer version of the Peacemaker, a BT-36, disappeared in mid-flight after taking off from an airfield on the east coast of the United States.

In the 2260s, Admiral Voysey cited the missing Peacemaker as an example of several vehicles which had mysteriously disappeared in Earth's history. Another example was a strategic hovercraft that disappeared in 1984 and a G-50X rocket plane which had only recently disappeared and then was recovered by the USS Enterprise (NCC-1701). 


 * While the hovercraft was seen in the Collector's museum, and the G-50X was found within a spacecraft operated by the Collector, the Peacemaker was not visible in the museum, leaving its whereabouts uncertain. The story was published six months prior to the date of the theft, so it was not intended to describe a real-world incident.
