Wouldn't get me up in one of those things though :)

Probably for the best. I don't think people with bad knees would appreciate the landing.

They do two flight times a day here, one immediately after sunrise and one in the 90 mins before sunset. Apparently winds are lighter and more predictable at those times than in the middle of the day. The balloons that used to fly near mum's house we always saw towards sunset (I was rarely up right after sunrise in summer to know!)
