The Smithsonian National Air and Space Museum in Washington, D.C. is home to a 19th century hang glider, the world’s first military airplane, and, as of June 28, the original Starship Enterprise. In case the museum hadn’t already made their excitement surrounding Star Trek’s 50th birthday this year apparent, they recently contracted linguist and language-creator Marc Okrand to record audio tours for them in Klingon, io9 reports.

Okrand knows Klingon better than anyone else on Earth. He first became involved in the Star Trek franchise in 1982 when he was asked to dub the Vulcan dialogue in Star Trek II: The Wrath of Khan. That led to him developing a complex Klingon language for the series and films, and eventually authoring The Klingon Dictionary.

Audio clips from the tour are now available to listen to on the Smithsonian National Air and Space Museum website or through the museum’s GO FLIGHT app. For a look at Okrand’s recording process, you can watch the video below.
