Tydirium/Legends

The Tydirium was an Imperial Lambda-class shuttle used personally by Darth Vader when he was taking Admiral Joser from the Alpha-Omega Prison to another facility.

In 4 ABY, she was stolen by Wedge Antilles during the Mission on Prefsbelt IV. Wedge, piloting a T-47 airspeeder, used stealth to infiltrate an outlying outpost of the Prefsbelt IV Naval Academy and killed a TIE Fighter's pilot. He commmandereed the craft and infiltrated the academy, where he narrowly escaped from the pursuing Imperial forces.

However, the Empire somehow retrieved the shuttle sometime later; possibly intercepting the shuttle before it reached the Rebel fleet. As a result, a team of Rebel Alliance commandos, during the Mission to Zhar, had to recapture the shuttle as part of the Alliance's plan to destroy the second Death Star.

The Tydirium, piloted by Han Solo and Chewbacca, was used to sneak past Imperial defenses and place a strike team on the forest moon of Endor to deactivate the shield generator protecting the second Death Star in the hopes of allowing Rebel starfighters an opportunity to strike the Death Star's core before it was activated.

After the destruction of the second Death Star, the Tydirium was used by Solo, Chewbacca, and the Katarn Commandos to board and capture the Imperial Star Destroyer Accuser.

Behind the scenes
The games Star Wars: Rogue Squadron II: Rogue Leader and Star Wars: X-Wing Alliance, the only two sources to detail the shuttle's capture, give conflicting information. The above account assumes both are correct and that both happened, possibly totally independantly of each other (given the briefing in X-Wing Alliance, it is possible those involved in its second capture were unaware of its first capture).
