Thomas Blair

Captain Thomas Blair was a Starfleet officer during the 2260s.

By 2267, Blair had risen to command of the USS Defiant (NCC-1764) when a cloaked under Romulan control played a game of cat and mouse with the Defiant by releasing probes while it was cloaked. Blair's reaction to the seemingly random appearance of the probes was to immediately think of the Romulans or Klingons as the perpetrators. After the incident, he filed a report on the incident that was reviewed by admirals at Starfleet Command. 

In 2268, he was still captain of the Defiant when it entered interphase and disappeared.
