It's a bird ... it's a plane ... IT'S A FOOT FALLING FROM THE SKY!!
A thrill-seeking double amputee lost his prosthetic leg during a jump in Vermont over the weekend -- and just when he thought it was gone forever ... A MIRACLE HAPPENED!
It all went down Sunday -- when Chris Marckres decided to go for a jump in Addison County, a popular skydiving spot.
Somehow, one of his artificial limbs became detached mid-jump -- and plummeted down to earth ... far from the designated landing spot.
"I think my adrenaline was so high and I was just so excited," Marckres told NECN .
