Fascinating footage of the remarkable Thailand rescue released today shows members of the group trapped in a cave being stretchered to freedom while seemingly heavily sedated and wearing wetsuits and diving gear.

The footage, released by the Thai Navy SEALs , shows a complex operation with numerous divers — both foreign and Thai — using pulleys, ropes and rubber piping to haul members of the soccer team to safety. The 12 boys were passed  “sleeping”  on stretchers through the treacherous passageways, a former Thai Navy SEAL told AFP Wednesday, giving the first clear details of an astonishing rescue mission that has captivated the world.
