Maroon (rocket)

A maroon is a type of rocket which makes a loud banging report (noise) and creates a bright flash. It is used as an alarm or warning. The British Royal National Lifeboat Institution uses these rockets to call the crew when the lifeboat needs to be launched.^[1] Another example was as a signal on a railway, to alert oncoming trains that they must stop due to unexpected accident or track work ahead.^[2] Used by British spotters in WWI located around the cities. They would fire when German bombers were approaching.
