Good points, and again calls into question the viability of the whole solar still things.
BTW, it was the "Lady Be Good," a B-24, and all 9 of the crew died, although one had managed to walk an incredible 111 miles from the crash site with virtually no water or food. Talk about the will to survive .... that was just one of those unfortunate wartime situations where SNAFU was the order of the day.
