Looks like it's a go - they've started laying out the balloon ready for inflation

It's going to take him around 3 hours to get to altitude so I assume he won't be jumping until at least 9pm uk time

2) I assume he will get up to top speed really quickly but at what point will he start to slow down to terminal velocity?
da fuq?
Why the confusion? I may have got the terms mixed up but he will be traveling faster than the speed of sound, as the atmosphere get's thicker and thicker he will slow down to the earths normal terminal velocity of around 200kph due to air resistance. Just curious as to what sort of altitude this would occur and would he notice that he was slowing down?

Only if he is alive!

Actually, when he's travelling fastest, he'll feel it the least.

There's no such thing - the term 'terminal velocity' describes the maximum velocity a body will reach falling under gravity, and varies depending on air density, the mass of the object falling, and the object's drag coefficient.

Even if you are referring to the particular case of the terminal velocity of a human body at sea level, then it can vary a lot depending on the attitude of the bodyand hence the drag generated - head down with arms at the side will fall a lot faster than in a spreadeagled position.

Fair enough, I always assumed probably from watching too many movies that their was an average velocity that a human body would reach in atmosphere while in freefall. I do know that pulling your arms in makes you go quicker as how else would the hero catch up to the bad guy whose just jumped out of the plane with the only parachute smile

1) How long do we reckon he will actually be in freefall?
Five and a half minutes, I believe.

The clock has stopped on the live feed but the camera is now focussed on the live activity...palpable excitement although the twitter feeds are annoying!

They also said tomorrow will be problematic so it may not be happening tomorrow aswell.

No, he's due back at work on Thursday. Boss wouldn't give him any more time off.
