Warning: the following contains distressing images.
There are images that sear themselves into the memory. The kind that reach through the decades and become emblematic of a particular moment in history.
A naked Vietnamese girl running, crying from her smoking village, her skin scorched by napalm. An Australian child steering a boat away from Mallacoota's burning shoreline. A sailor planting a kiss on a stranger at the end of a war. An unimaginable act of terror that started another.
A photograph taken at Kabul airport on Sunday shows 640 Afghani refugees crammed into the belly of a United States military C-17 transport plane, an aircraft designed to fly with half that number.
Most are men, many of whom likely aided the US in its battle against the Taliban in recent years. But women and children are scattered among them, too; one cradling a wide-eyed baby sucking on a bottle.
Then there's the footage.
Hundreds of Afghan people sprinting alongside another US military plane evacuating people from Kabul airport on Monday.
Some among the desperate throng attempt to wave down the pilots, pleading with them to stop. Others search for a way onboard the moving plane, even trying to scale the landing gear, choosing to risk their life thousands of metres in the air rather than endure one under their country's new government.
