Ah, no they wont.  You guys are saing that air resistance will cuse the iron bar to hit the grouwnd first if they are attached but magicaly the air resistance does not exist when the bars are not attached?

What ever the material.  The heavier bar will hit first.

Sorry, can't resist..

Actually, the objects did fall at different speeds from the Leaning Tower.  But they all appeared to land at the same time.  If dropped from a greater height, the difference becomes more pronounced (air resistance).

Air resistance and bouyancy will both cause the less dense end to hit last.

Once the aerodynamic drag cancels the gravitational accelleration terminal velocity is reached.  Terminal velocity for two equally shaped objects with different densities will be unequal, the denser object reaching a higher speed.

Bouyancy is a minute force in air but in a heavier fluid could have large consequence.
