Fortunately, Eideard, lots of people in Yuma actually have indoor plumbing these days. The incidence of urinary tract infections has dropped dramatically. “You don’t even want to go outdoors to pee in Yuma in the summer.”

It would actually be a quite comfortable 76ish by around 11,000 feet. The actual numbers might even be more extreme since the air would probably cool down faster due to lower humidity. Granted the people on the ground would probably be pissed that they had to step out and launch the thing but pointing out the harsh conditions is a bit misleading. Still a pretty interesting technology. What ever happened to the solar powered flying wing NASA was testing out in Hawaii? I know one of them broke apart but I thought they had two.
