Ah, 23 minutes till launch, midnight tonight if I'm right in what I just heard...

 

Not quite, they run two clocks...

 

One is a real clock, the other is the launch clock.

 

The launch clock which is one you are seeing is paused at certain times for activities to take place.

I can only imagine how terrified I would be strapped on top of a bomb that once you lit, there's no turning back.

 

Heros all :respekt:

 

Update... just had a little problem but are good to go in 9 mins.

 

Not only that, but they don't even fly the damn thing, it is controlled from the ground :) Given a chance, I'd happily do it, in fact I'd love to do it. It must be the adrenalin rush of a life time. 7 million pounds of thrust.... now that is some serious ummmphh
