ARES meaning in Academic & Science ?

Communication failures have been a defining part of natural disasters and even some human-generated events such as the September 11 attacks that occurred in New York City in 2001. A lack of communication between firefighters at the World Trade Center contributed directly to the deaths of 300 of those firefighters. Amateur radio provides a means of communication "when all else fails".
