Both Delta Air Lines and United Airlines retired their fleets of jumbo jets in 2017.
Retired planes are usually sent for storage before being sold, brought back into service, or scrapped for parts.
A picture posted on Twitter shows one Delta's 747-400s being scrapped.
With the retirement of Delta's fleet of jumbo jets in December, there are no 747s left in passenger with any of America's major airlines.
And there's no better reminder of this than a photo posted on Twitter by Royal S King showing the skeletal remains of a Delta Air Lines 747 as it is being scrapped at an airplane junkyard in Marana, Arizona.
It's a jarring visual that shows the fate that befalls most of these majestic beasts.
