Two iron weights, one twice the mass of the other, are dropped from the top of a building. compared with the lighter weight, the twice as heavy weight will hit the ground with?

If we neglet air resistance for both objects then both will fall parallely(at same time) because time taken by both objects is independent of mass. there is famous experiment i.e"feather coin experiment" . normally we think that heaver objects falls faster but this is wrong concept. it depends on medium in which objects are moving.
