Though my question was generic, my particular interest is in post-hurricane impact assessment. Recently FAA has relaxed restrictions somewhat and so I am interested in what types of sensors are available for civilian use. I'm thinking that UAV's, especially high and slow-fliers that can remain aloft for several days may offer serious alternatives to traditional sources. I understand that NOAA has purchased about 30-40 of the birds; mostly to acquire physical data at a higher spatial and temporal resolution than hurricane hunter aircraft are capable of providing. This brings us full-circle to your dad's interest, since NOAA provides navigational charts for both civilian and military use.

My interest is in both operating parameters of the platform and also civilian sensor packages. I don't need a Hellfire missile, for example. Not that I would turn it down if I could pop that pickle loose on some inanimate object!
