If someone jumped off of a building, and were tackled at full speed right before they hit the ground, would either party survive?

I was arguing with my friends recently about this; I will attampt to explain.

Someone jumps off of a building and is travelling at a speed that if they hit the ground they would die no matter what.  

If someone came from the side and tackled the falling person at the last second (maybe 2-5 feet above the ground), would either of them survive?

It would be hard to tackle them in any meaningful way without exerting an upward force.  A person falling 100m will only take about 0.03 seconds to travel that last meter.  If no upward force occurs, that tackle will be little more than a nudge, which will be of no benefit to them, and little harm to our would be linebacker.

If upward force occurs, the person's deceleration will be spread out over a greater distance (1 m vs. a few mm) which would improve survivability.  That will come at the expense of the linebacker, who would be absorbing the blow.

The most likely outcome?  Even if the linebacker did everything he could to reduce the fall, the person will likely die if falling from a signficant height.  The linebacker faces a lesser, but still pretty serious risk.
