#information message
maybe in order to draw more attention to an ongoing SAR operation, the game system could annouce it in chat similar to dealership and job refreshes. the system could probably list which airport is hosting the operation, and maybe the general direction of the operation, and also could potentially provide updates for the operation/whoever decides to join/leave
An example could be smthn like
Searching for disaster victim(s)
System
"Ongoing maritime search and rescue operation conducted by Hyperant southeast of Tomfoolery airfield, additional assistance would be appreciated."

System
"Ongoing maritime search and rescue operation conducted by Hyperant southeast of Tomfoolery airfield has found & identified disaster victims, Medivac aircraft requested"
