As you may recall my wager with SM, which I think he chose not to pick-up:

I put my money where my mouth is and bet a case of single malt whiskey that there would be no more than Six further shuttle flights.

I actually believe the true figure will be rather less than that - suspiciously close to zero, in fact...

I also believe that there are strong economic and scientific grounds to accept the inevitable now, and stop wasting money on something that won't work, and begin using it sensibly on something that might.

It will concentrate NASA's bureaucracy wonderfully if they don't have anything that works so that this time they HAVE to make something that flies, rather thasn another X-machine that is testing something unneccesary, without the actual need for it to work.

Just my jaded opinion, of course...
