From Aviation Week: Video has emerged on YouTube of a March 23 incident where a cleaning truck run amok slams into an unmanned UPS Boeing 757-200 (N462UP) on Spot 90 at the Miami International Airport. Sources tell Aviation Week that no crew members were aboard the 757 when the truck, driven by a cleaning vendor employee, hit the left side of the aircraft, causing punctures and other damage. An investigation is ongoing as to why the truck did what it did, but it appears the driver is relatively unhurt, based on the video. The aircraft was taken out of service that day, fixed by AAR Aircraft Services in Miami and returned to flight status on April 13
A UPS spokesman says it appears that the driver "hit the gas instead of the brake pedal" when maneuvering near the 757.
"To ensure that the aircraft was safe to fly, it underwent extensive skin and structural repairs before returning to service, just in time to carry plane loads of flowers from Central and South America for our Mothers Day customers," he says.
