Here's a toast to my two tourists, who died for unexplained reasons. I'm hopeful that you might be able to provide some insight into why they died.
After a successful tour of the moons of Kerbin with stops on the surface of both Minmus and the Mun (as well as an emergency refueling in Kerbin orbit on the way home), my six tourists and one pilot were doing well under parachutes coming in for a nice splashdown right next to KSC. Descending at a rate of 8.0 m/s, the Large Tourist Ferry (clever name, eh?) splashed down and the ship survived intact. Unfortunately, two of the tourists in the PPD-10 Hitchhiker Storage Container (which took the brunt of the splashdown) were killed, while two others survived.
As you might imagine, this was a traumatic experience for the two surviving tourists, and not great for the two dead ones either. While this hasn't seemed to decrease the demand for space tourism, I'm wondering how to avoid such a fate in the future. (Although maybe the simple solution is to just add more Mk2-R Radial-Mount Parachutes, perhaps four isn't enough.)
