Only a insane person would what to pay the extra freight required to get the cargo there a few minutes earlier. But, as a contest, it's the last reasonable "Around the World" record to be broken at some time in the future. It's also a reasonable contest as the vehicle that can do it, will have many of the attributes of the vehicles that will be used to go to orbit in the future. Of course, you could go faster, but now you talking about more than one gee on the passengers and eventually you'll squash the passengers. So, humans having grown up in a one gee environment, it makes for a nice break point for the last "Around the World in ??????" record. :-) Craig Fink
