Joining a team of mechanics responsible for stripping down and rebuilding the biggest aircraft in the U.S. Air Force's arsenal - the Lockheed C5 Super Transporter - Zdenek discovers what it takes to get 380,000 pounds of plane, plus its cargo, up in the air and back on the ground in combat zones. Inside this mammoth warehouse with wings, Zdenek sees how ingenious engineering overcame the design flaws that once grounded the entire C5 fleet, and the extreme forces that still strain the plane every time it takes flight to allow the Galaxy to play a critical role in conflicts from Vietnam to Afghanistan.
