In the SouthEastern US we have some "itinerant" repeater pairs on the 440 and 900 ham bands. We don't have those on two-meters, but if your coordination body has not made provisions for "portable" or "temporary" repeaters, consider that the "flying" repeater scenario would fit in well using such planned portable repeater frequency allocations or assignments. Also, repeater hardware on these higher frequency bands would be better suited to flight space and weight needs than equipment on lower frequency bands. A "flying" repeater operation would be very effective if it were part of a well prepared emergency communications plan.
