...the Earth does not move. If it moved, we would feel it moving. That's called empiricism, the experience of the senses.

He's got a point you know. I've said all along that trains and aeroplanes don't move, they move the earth instead.

Aside from the acceleration at take-off, banks and turbulence, an aircraft flight is perfectly smooth, you can't feel it moving so obviously it isn't, that's called empiricism, the experience of the senses, as brownback quite rightly pointed out.

The feelings you get when you start a flight or change direction are just the resistance put up by the earth against our attempts to shift it. The earth, being rather large does not like being moved by our small our aircraft, so it resists, causing turbulence.

Ah, but you ask, what about all the people one the ground that see the plane move? Well, that's simple enough, the aircraft I am on also has to move them, or the entire universe would just get knocked of centre, so they "see" the plane move, when in reality, it is they that are moving.
