On Thursday, April 25th, The Charles M. Schulz – Sonoma County Airport will be conducting its Triennial Emergency Response Exercise. The exercise is an elaborate, unrehearsed safety training that takes place every three years at commercial service airports around the United States. Communication, incident command, and coordination between multiple agencies are all put to the test; opportunities for improvement are identified and remedied. There will be activity all week at the airport, along with Thursday's training.
