It's pretty much the same plan for any fire...sparked by a 2 stroke motorcycle, a campfire, downed power line, chainsaws hitting a rock, kids playing with matches or illegally dumped fireplace ashes.
Someone will see the fire and smoke and call 911. The fire department will respond in a timely manner along with other county stations, the USFS and CalFire and the fire will go out eventually.
If it's any consolation, the KMAX helicopter being used has an extraordinary safety record as does the company. They have been flying six days a week in Big Bear (removing bug trees) for the past two years without incident. I can assure you that the pilot and ground crew have a vested interest in insuring that the above plan is never implemented because of them.
