747-8F World Record
I filmed this video at Houston's George Bush Intercontinental Airport (north freight ramp) on July 5, 2013. The cargo was well within operating limits for the aircraft and posed no danger. 747-8Fs can safely take off much heavier than this, as the cargo only set the record for the heaviest single piece carried, not the record for heaviest takeoff. Departure was normal and smooth and the cargo was delivered to the destination safely and one time.
