think about it this way... imagine a shopping trolly on a conveyer belt that moving 10000000000million miles an hour.. because the wheels free move... the trolly remains stationary... if you sellotaped a rocket to it... it would move...
if you put a sail on it.. +bit of wind .......it would move..
Infact.. a strong wind... it would move... the wheels are completly INDEPENDANT from the trolly...
In this case being a plane... That was very good RIK... it fools us because of the way its been cleverly worded...
