just a clone thread.
th original riddle:
Quote:
A plane is standing on a runway that can move, like a giant treadmill. When the plane's engines throttle up, it begins to move forward, but the treadmill is made to match the forward speed of the plane, only in the opposite direction. So, as the plane moves forward, it moves backwards beneath the aircraft.
As the engines throttle up, does the plane take off?

translated into reindeer and sleigh dynamics, the question takes on other aspects:
A sleigh and 8 tiny reindeer are standing on a runway that can move, like a giant treadmill. When the tiny old elf sprinkles the magic dust, it begins to move forward, but the treadmill is made to match the forward speed of the sleigh, only in the opposite direction. So, as the sleigh moves forward, it moves backwards beneath the reindeer's feet.
As they dash away, dash away, dash away all, does the sleigh ,as dry leaves that before the hurricane fly, when they meet with an obstacle, mount to the sky?
