How do you summon the courage to jump from a balloon on the edge of space, hurtling faster than the speed of sound towards the earth? Felix Baumgartner did just that on Sunday night.
Looking at the facts and figures from his jump what can you tell us using your maths? e.g. He accelerated to a speed of 833.9mph this is XXXXkmph. I could travel to London/New York/Australia in X minutes at this speed.
