I recently discovered that the STS Orbiter (and therefore the ISS) was built to hold a cabin pressure of 14.5 PSI near sea level conditions. I had previously assumed that the shuttle was built with the 8 PSI differential that most jet airliners are designed for.

This change must have added a lot of weight to the orbiter. Structure, particularly the windows all had to be strengthened considerably for that extra air pressure. This seems to be a costly design choice in such a weight critical spacecraft. While sea level air pressure is a big advantage, especially for a normal 78/21/1 atmosphere, I wonder why they couldn't get by with a lower pressure/higher cabin altitude.

We do just fine flying airplanes breathing basically 8000 ft earth air, why do much more fit astronauts need sea level air at the expense of probably a couple tons of launch weight.

Stuart has just played *Inspector Norse* by Todd Terje. As soon as I heard the opening beats and electronic bleeps, I thought to myself that it is a typical Maconie tune to play when he's fronting another program. Not a criticism at all, I quite like the tune. It's just one I wouldn't expect Craig to play.

That got me thinking about how Mark Radcliffe (semi) regularly plays *Fanfare* by Eric Matthews when he's covering shows.

What other songs do you associate with presenters - ideally when they're covering a slot, but I'm happy to open it up to things they regularly play (like MAH and Squarepusher or Nils Frahm).
