Mission has resumed... they're now laying out the balloon. I hope it goes ahead!
Tony, good question, i guess because he can? There are so many things that i often wonder why, but then equally, why not! I have friends that have acheived world records & firsts, in the aviation world, and put thier lives in stupid amounts of risk/danger (in my opinion) but to them its half of the fun/challenge!
There is one thing for sure... I would NOT do it!

I'm intrigued to see the parachute system that's going to stop him from almost 700mph! I imagine there will be a hell of a lot of deceleration involved. Speaking of non-Aston related cool things, I saw this today:   A 50% scale Lego Rolls Royce Trent 1000 jet engine. It spun round and everything! I was impressed to say the least (not to mention jealous that I never got to build something like that when I was an apprentice!).

He'll slow down without a parachute when he hits the tropopause - about 35,000ft. It's at that stage the air gets suddenly very much thicker, it'll be like hitting a swimming pool ful of thick jelly! He'll slow to about 150mph, and probably get very hot! Parachute only required for the last bit.
Still, what an awesome adventure.
Edit; George, just noticed that you're an aerospace engineer.....!

Still, what an awesome adventure. I take it he has some special heat resistant suit then? I'd have thought he would have slowed down before he went through the troposphere just to stop the build up of heat.

Not sure any retardation would be effective with the lack of 'air' prior to the tropopause. Looks like he's wearing some sort of astronaut suit, must be heat resistant. Just about to be featured on BBC news, so ill keep you updated!

Cancelled due weather. Shame, I'm now really intrigued......

Just about to be featured on BBC news, so ill keep you updated! There's still ozone though so I suspect they could slow down a bit if they wished to. Not sure how thick it is though. I'm just trying to think of ways they could get round the immense heat that would be generated by slowing down via friction of air! Will be a shock too as I bet the suit will have to be heated to stop it freezing when at the higher altitudes. Look forward to seeing it when they re-attempt!
