That's David Eun, a Samsung exec, so he was probably up front in biz class.

the front section of the plane is theoretically the most dangerous part of the plane; survivors in plane crashes are most likely to come from just behind the wing.

That greatly depends on the type of crash. The added risk your talking about has a lot to do with nose down collisions.

I'd factor in the fact that the people density is lower up front, probably aiding you in getting off the plane faster.

There's no need to factor in anything, those statistics come from actual outcomes of past crashes.
