No smart arse, it's to illustrate how changing weight distribution affects an aircraft and how it is dealt with, either by the pilots if being flown manually or by the automatics if engaged. The person asking the question is obviously not a pilot so I've kept the explanation as simple as possible. I've avoided using complicated technical terms such as centre of pressure, angle of attack,formulae for lift and why a rearward CofG is beneficial in certain situations but detrimental in others.
