Edward Michael "Bear" Grylls

In 1996, he suffered a freefall parachuting accident in Zambia. His canopy ripped at 4,900 metres (16,000 ft), partially opening, causing him to fall and land on his parachute pack on his back, which partially crushed three vertebrae. Grylls later said: "I should have cut the main parachute and gone to the reserve but thought there was time to resolve the problem". According to his surgeon, Grylls came "within a whisker" of being paralysed for life and at first it was questionable whether he would ever walk again. Grylls spent the next 18 months in and out of military rehabilitation at Headley Court before being discharged and directing his efforts into trying to get well enough to fulfil his childhood dream of climbing Mount Everest.
In 2004, Grylls was awarded the honorary rank of Lieutenant Commander in the Royal Naval Reserve.
