From the guy who did it and uploaded it:
I BlackShadowMist pull off one of the luckiest sticks in Halo 3 history, which boils down to total insanity. A Cross-Map, off wall, air lift, sticky. With 99.999% of luck involved. Cannot reattempt and succeed

Hey man nice shot!
This post got me fired up to play some Halo. I was contemplating leaving work early after remembering the glory that can be achieved.
SICK! I’m firing up the 360 now.
