@calfireaeu: That aircraft you’re watching is an Aerial Supervision Module, or ASM. When multiple aircraft are working over a wildfire, the ASM serves like the command post in the sky. The aerial supervision crew coordinates airtankers, helicopters, and other aircraft, helping direct airtankers where and when to drop retardant while keeping track of the aircraft working over the fire. This ASM launched from AEU’s McClellan Airtanker Base today with three airtankers headed to the Bull Fire in Nevada. #CALFIREAEU #AerialFirefighting #Wildfire #Firefighting #McClellanAirtankerBase
