Fire Detection and Suppression Systems.
Aircraft fires are one of the most hazardous and dangerous situations that can occur while flying. In order to mitigate the risk of an aircraft fire, fire detection and suppression systems were implemented. Fire detection systems can let the pilot know which section of the aircraft is on fire so he can plan accordingly. Fire suppression systems help put the fire out and can work hand in hand with fire detection systems. When a fire is detected a fire extinguisher that is built into the aircraft can automatically go off to put the fire out before it gets out of control.
This accident occurred due to an in-flight fire United Air Lines Flight 608 in 1947.This is the report https://reports.aviation-safety.net/1947/19471024-0_DC6_NC37510.pdf
Need to discuss how a fire protection and impression system could have prevented this accident from occuring
