Da Vinci's glider
From Memory Alpha, the free Star Trek reference
Da Vinci's glider was a mechanical flying apparatus invented by Leonardo da Vinci.
In 2374, USS Voyager Captain Kathryn Janeway and the Leonardo da Vinci hologram from one of her holodeck programs attempted to launch a prototype of the glider from a bridge in Florence. They immediately fell into the Arno and had to retreat in embarrassment to da Vinci's studio.
Later, when the hologram was stolen from Voyager by spacefaring pirates and outfitted with The Doctor's mobile emitter, he spent several days on a trading center planet, where he rebuilt the glider using duranium. He and Janeway used it to escape pursuers after they had recovered Voyager's stolen goods. (VOY: "Concerning Flight")
