Durri Kruger is an excellent engineer and pilot. The best in the entire Rebel Alliance. His skills in engineering are far greater then his piloting skills but don't let that fool you!
Durri is especially skilled in flying co-pilot ships, with one person as the pilot and the other as the gunner and being able to switch these positions at the same time.
Kruger is a professional, but he is young and new to the Alliance so sometimes he gets picked on because he has better skills then most. Still Durri Kruger is formidable addition to the Rebel Alliance.
