if you could design a plane to safely land upside down would the earths gravity feel as if its pulling you upwards for a moment. If not what would you experience as you adjust?
Surley you wouldn't just suddenly flip fight over as there is nothing to determim which way you would tern but it has to happen some how but how?
The steeper the road, the slower I cycle - to the point where I am reduced to walking speed. Is there a gradient beyond which the mechanical advantage offered by a bicycle diminishes to the same (or less than) walking?
It's Bonfire Night here in the UK tomorrow, a time when there are lots of stray fireworks in the sky. This fact, coinciding as it does with my flying off on holiday for a few days, prompted me to wonder just how much damage would be done if my plane was hit by a wandering firework - during takeoff of course, when the plane is at a low enough altitude to be hit.
