I have lived in the Austin, Texas are now since 1995. In that time if have witnessed many times why this part of Central Texas is referred to as Flash Flood Alley. For at least 100 miles North and South of Austin along IH 35 the residents have had to adjust to prolonged periods of drought interrupted by torrential rainfall and flash floods. It is a way of life here.
Drone and sensor technology could be an amazing boost to emergency response capacity - from high altitude phone repeater and mobile emergency broadcast antenna to infrared debris search agent, helping to locate trapped casualties. Another way to re-purpose early generation military equipment, and also employ former members of the military in a vitally important support role.
