Tourist, you may say it.

Right. From my schoolboys book of basic physics, Terminal velocity is derived from the square root of 2 x the object's mass x g (nearly 10 m/s/s) all divided by the density of the fluid (air) x the presented area of the object times the drag coefficent.

In the case of a human body, a canonball and a broken remote control aircraft, a lot of those funtions remain the same. So you tell me if a canonball with a big mass compared to its presented area will fall faster, slower or at the same speed as a human body. And then extend that argument to the RC aeroplane.

Do the maths. You'll find there is a big difference.
