If you are neglecting air resistance and the velocity of the plane remains constant after the bomb is released, then the bomb's horizontal velocity remains the same and it must land directly under where the plane has moved to when it impacts the ground.
If you include air resistance then the horizontal velocity of the bomb is reduced compared with that of the plane and the bomb must land at some distance behind the plane.
Air resistance is generally treated as a force proportional to the square of the velocity directly opposite in direction to the total velocity of the object ( vector sum of is horizontal velocity and the vertical velocity resulting from the effects of gravity on the bomb) and the constant of proportionality is dependent on the cross-sectional area normal to that velocity.
