Boeing mechanics cause $4 million in damage to Air Force One, report finds
WASHINGTON (CNN) -- Three Boeing mechanics caused $4 million of damage and could have sparked a mid-flight fire while repairing one of the planes in the Air Force One fleet, a federal investigation has found. The oxygen system aboard one of the two VC-25 aircraft available to President Donald Trump was contaminated while the plane was undergoing maintenance at a Boeing plant in San Antonio, Texas between April 1 and April 10, 2016, according to an incident report released by Air Force investigators this week.
