To Move Or Not To Move

This is one of Air Methods' EMS helicopters, post-Joplin tornado.   There is a back story to it I'm sure, as there always is, but one has to wonder why the pilot did not relocate his three million dollar aircraft to somewhere else, unless the severe thunderstorms were unforecast which I highly doubt.  While hangaring it might have produced the same result given the widespread devastation in Joplin, at least there would have been a plausible, reasonable effort to protect the helicopter where now it appears there was none.   And somewhere in the debris of that hospital is an Air Methods' hazardous weather plan, directing the base on what to do in inclement weather, which if I had to guess "leave the helicopter where it is" was not one of the options.
