This is like aeroplanes which as we all know become weightless at takeoff speed, everything in and on that aircraft also becomes weightless, you could even unbolt the engines and they would stay there, bolts are there for when the plane is on the ground. Why don't passengers float around I hear you ask? Well, the answer is simple, air is pumped from the ceiling and through ducts under the floor to push people down, to enable astronauts to practice weightlessness in aircraft the air pumps are turned off. If a vertical tube could be fixed to the underside of an aeroplane then passengers could float down to the ground and step off (if it wasn't travelling at high speed that is). Experiments are already being carried out with rescue helicopters to replace the winch with a telescopic tube allowing the rescuer to float down to the casualty.
ETA: Bizzard and Gibbo will confirm all this.
ETA further: Gibbo have you made any progress with your zoomable 3D Smartgauge display?
