man was late for his flight, so he got into the jet bridge(which was already
closed by the gate agent) and proceeded to jumped off, trying to get to his
plane.

unfortunately, he still missed the plane, as shown in the pics below.
he was apparently injured as a result of the fall.

Google Translate doesn't do a very good job, but I think the pictures
speak for themselves. This incident took place at Nanjing airport(NKG)
in China.
