Biking down metro escalator

Guy takes ride down the hill. Escalator length 51m / 167f, angle 30^0 Unhopefully, either because of speed and angle or cause of number of people getting into his way he had kinda bad landing downstairs, which except for funky rotation while leaving the stairs is left to be unseen due to placement of cameras. He reportedly landed after few more meters of fly and was taken to hospital with spine fracture suspicion.
