Rescuers painstakingly installed a complex series of 15 professional pulleys to slowly hoist John out.

They managed to lift him up just a few feet, allowing him to hear the voices of support from the crew.

But in a heartbreaking moment, the heavy pulley anchor completely failed in the absolute dark.

John instantly slid back into the narrow crevice, wedging himself even deeper than before.

To even attempt to pull him through the sharpest bends, rescuers realized they might have to break his legs.

It was a grim necessity that John reportedly agreed to in his desperate wish to see his pregnant wife and children again.

“I really, really want to get out,” John told his brave rescuers through the tight rock walls.

His immense resilience during the 28-hour ordeal, even singing songs to keep spirits high, remains a testament to human endurance.

But despite the monumental efforts of the 137 rescuers, the physical toll on his upside-down body was too much to bear.

After a long and agonizing battle against geometry, John tragically passed away deep underground.

Following his passing, a very difficult decision was made by the state authorities and his family.

Because his body could not be safely recovered, the entire cave was permanently sealed with thick concrete.

It was turned into a permanent underground tomb and a sacred memorial for the young explorer.

This tragedy served as a global wake-up call regarding extreme cave safety and the importance of physical limits.

It reminds us that while curiosity is the engine of human progress, it must be tempered by a profound respect for the natural world.
