Well no new progress, just not getting the time with the way fire season is starting up. All of our engines are being staffed 5 days a week due to staffing shortages which means we are really working 6-7 days a week which isn't leaving much time for building.
Bondo, the ex subchasers are the only older tankers still flying. The P2V Neptune and P3 Orion are flying for the feds, the S2 Tracker for the state.
Of course the DC10 is out there too but that is a completely different creature. In SoCal you will also run across the CL415 "super scoopers" on occasion.
The military C130 "MAFFS" have also been activated. (MAFFS Modular Airborne Firefighting System).
